anamorphic widescreen dvds wont show correctly on widescreen tv
I have old anamorphic widescreen dvds that play and show video on my widescreen laptop correctly, but do not display correctly on my tv (also widescreen). On the tv, black bars are added, and cut off what should be shown to the left and right, as if my movies were originally 4:3, when they are not. So I am wondering if there is an easy converter out there for each dvd, so that these movies will display correctly and show everything on a widescreen tv (so that the dvd will no longer be anamorphic)? At first I thought a simple ripping program might work, but I have been told the anamorphic data would still be added, and I will have to convert from one dvd type to another for my tv to display it right.
Any recommended easy programs, if this is true? thanks |

Is the picture also squished vertically?
I think most TVs have a setting to force a 16:9 aspect ratio. While I can't say I've messed with it, I think the setting in my TV is named "auto wide". If not it should be possible to rip the DVDs and change the aspect ratio in the process. I think sometimes for reasons I don't understand it's the player which gets it wrong (I've had anamorphic DVDs display as 4:3 on the PC a few times). As I generally don't create DVDs I couldn't explain the process, but if you can't manually force 16:9 using the TV's settings, I'm sure someone clever will come along.... |

Most players have these 3 options: • 4:3 Letterbox • 4:3 Pan & Scan • 16:9 The tricky thing is, although obviously only 16:9 setting should be used with a widescreen TV, using 4:3 LB or 4:3 PS setting may not cause much trouble most of the time. Why? Because many DVD-Players generate a WSS signaling line that tells the TV to automatically zoom the picture that has been letterboxed by the player which is actually playing an anamorphic DVD. To the viewer this looks correct (although there is a vertical resolution loss of course). Even if you select PS in the player's settings, many anamorphic DVDs do not allow PS because the video needs to be suitable for that so they letterbox anyway. Until you come across an anamorphic DVD that does allow or even force PS - as soon as this happens, the automatic zooming will no longer work since the picture is not "player-letterboxed" anymore and you get what you described. The top & bottom bars are probably because the movie is in cinemascope (in other words there are top & bottom bars on any display, it's their size that varies).

http://www.thedigitalbits.com/articl...ic235demo.html From your description these DVD's are not anamorphic but letterboxed and authored 4:3 ie widescreen movie fitted into a 4:3 frame. Modern anamorphic DVD's will show correctly on a widescreen 16:9 TV. Previously to making anamorphic releases DVD's were authored to the prevailing majority TV's on sale ie 4:3 and widescreen material like movies that were shot 2.35:1 were fitted into a 4:3 frame hence the postage stamp view on 16:9 displays. On your standalone DVD player there should be a setting to indicate what sort of TV display you have maybe it is set to 4:3? On a computer depending on the software player this will/can be corrected. As an example this is a MediaInfo report on the Cinemascope DVD release pre anamorphic Code:

thanks for all the replies the dvd box states widescreen, but it was the dvdcompare website which stated one disc as having a picture format of anamorphic, 1.78:1, widescreen, for the region I have. I mentioned 'old' as one particular movie with the same issue was released in 2001, which I suppose was when 4:3 were still the majority of tvs. The dvd player definately sees this movie as 4:3. Thanks for the mediainfo suggestion, I have the info here for one disc, and as in the last post, its 4:3 for all vob files on the dvd.
The entire movie has black bars when played on my standalone player. I can tell instantly that theres a cut off as very large lettering on screen, eg an intro of "Warner Brothers presents" (which shows on the pc with no problems) only shows as "ner Brothers presen" on the standalone. The lettering is correct in size, not squashed or stretched. So it would seem that the problem is with my standalone player not understanding this, as in the last comment. So is the solution to simply find a better/more up to date standalone player that understands similar older 4:3 discs? Setting the movie to 16:9 or auto on the standalone shows the movie with the added black bars. |

What is the brand and model number of your DVD player - it sounds like it might be set to 4:3 in the settings? However what I have done with the couple of widescreen non anamorphic DVD's I have is to rip them to hard disk and then reencode them in ConvertXtoDVD (most DVD authoring programs can do this so you are not restricted to ConvertXtoDVD) setting the authoring parameters as 16:9. This stretches the image horizontally and vertical maintaining correct aspect ratio. If the original movie was shot in 2.35:1 aspect ratio then of course on a 16:9 TV there should be black bars top and bottom.
By re-encoding ie enlarging the the image will result in some quality loss but depending on how important it is to you it at least gives you a backup copy of your DVD that doesn't require re adjusting your DVD player and or TV. Re MediaInfo if you set it to TEXT you can copy and paste the report in full without having to do a image capture etc...

my dvd info (not sure how to do the scrolling text)
http://www.mediafire.com/?w9x4x7fxuzcz4i0 I have tried the dvd above on a 4:3 tv - it shows with no bars at all, left,right,top or bottom ..as expected, its unstretched with the far left and right obviously not in view, and takes up the entire screen. Im using a Bush player, model 2028. It can play my other widescreen movies with no issues, black bars only ever top and bottom on a ws tv or non ws. The player has been unlocked with the remote to play imports-and the dvd shown here is one. At first I thought this could add to the player not being able to fully understand the disc, but as you say its prob a case of the player not understanding its a widescreen movie created in 4:3. This is the first time Ive come across one. The only thing im not sure of now is how many players are able to understand/correct my movie for a widescreen tv. If I zoom out on the widescreen tv (using the dvd players remote), I see the movie fully in widescreen perfectly, in a box. Unfortunately it zooms out too far to be watchable. So I blame my player If I 'zoom' out using the dvd players remote on the 4:3 tv, I just see the 4:3 image in a box and nothing else. The ws left and right elements are missing. Thanks for the tip on convertx, I forgot I may be able to correct it if I can work out the correct settings. I thought the dvd player might be auto setting itself to 4:3 for specific movies of an unusual aspect ratio (the movie above is supposedly 1.78:1 according to dvdcompare instead of the more popular 1.85:1)? The box itself on its case shows a widescreen logo. there are no options to enforce a ratio using the player or on the movie menu, only on the tv-which doesnt help. convertx or a similar problem should work, even if i get a poor quality output. ill just need to make sure I use the right settings, and it doesnt take too long ps I say movie in the lightest sense after seeing trailers/clips as one of the imports, from above, is shaolin soccer, hk region 0 comedy http://dvdcompare.net/comparisons/film.php?fid=2422#1 This is where I got the screen ratio and anamorphic suggestion. thanks for the help Last edited by AceRimmer667; 19th March 2012 at 13:33. |

You need to disable any zooming on your player which will give you black bars all around the picture. Then you take your TV's remote and switch the display mode from auto to "16:9 zoom". This is all that's needed! This will display it perfectly sized (no bars at all if the movie is 1.77:1). However, if your player is upscaling to HD there will be problems with that. First, many TVs do not offer "16:9 zoom" if a HD signal is being displayed, and second, it means that your player is pillarboxing the image (bars on the left + right) so that "16:9 zoom" doesn't work as intended. If either one is the case you're screwed. No way around re-encoding then. Or get another player. Last edited by TheSkiller; 19th March 2012 at 14:36. |

thanks for the last couple of polite replies. I will assume some people are now at work
1 - The bush dvd player is already set correctly-it does not have a large list of options to set. The screen can be set to auto,16:9 or 4:3. I set it to 16:9 for the widescreen tv, this cuts off the left and right hand side of the image (of what would have been the correct result if it had not). 2 - For the same movie on a 4:3 tv, it shows in full screen. The areas that would normally be visible on a ws movie to the left and right, are cut off. There are no black areas, and the image is not out of proportion. So the dvd on the 4:3 is showing as to be expected, as according to mediainfo, it is actually 4:3, despite stating on the dvd box that it is widescreen. So if it was not stated as widescreen, this result would be acceptable. 3 - The only way to fill out the entire screen (no black left or right) on the widescreen tv, is to zoom.. but the image is therefore cropped. I am only concerned about the movie showing in full on the widescreen tv with nothing lost to the left or right. The zoom function on the player in either case above, has NOT been touched. This is the only movie with problems. So the problem lies with the player, the TV cutting off the image, or having an incompatibility with one another. thanks |

Maybe it's how the movie is formatted.
Lots of them are widescreen but already letterboxed (the mattes are present and seen on a 4:3 TV but a 16:9 TV must zoom the image). For a 2.35:1 movie, there will inherently be mattes, as the DVD accepts only 4:3 and 16:9. I would let it first to AUTO, then I'll try 4:3 (it is sometimes equivalent to FULL).

Yes, please do that.
There aren't too many ways how the video of a DVD can be formatted. What came to my mind is: MediaInfo probably reads the DAR flag from the actual MPEG2 video, not from the IFO files. Now this actually does matter because only the IFO files instruct the player what to do. If you'd check the VTS_01_0.IFO using IfoEdit it would give a definitive answer to the question how the DVD is formatted flag-wise and what display modes are allowed/forced if it's an anamorphic video. |
