Glare? on dvd images

[cigarband]

I'm not sure which forum to post this to so i'l put it here. This is more of an annoyance than an outright problem. I have been burning DVD's for a few months now and I have used a lot of different programs, imageburn dvdshrink, dvddecripter ,fabdecript, Nero this, nero that, -r, +r, +r DL, + -RW dvds
But the one thing that i have noticed about ALL of the dvds that
i have made is the glare. The on screen image always seems to
have an area where the the light is of a higher intesity than in the rest of the image and that area seems to almost always be completely saturated in light, no detail just white glaring light.

If this were a Jpeg i could adjust it any number of different apps
photo shop, gimp, etc., but this is the image that is on TV after the burn, the image i see on the computer monitor shows non of this, i could adjust the TV monitor to compensate for this but ( my wife kind of has a cow whenever i start adjusting the TV) thats just treating the symptoms not the cause.

I think it might possibly be my burner, but i hope not. I'm
using a LITE-ON DVDRW SHW-160P65 Windoze 98 SE
Compaq 5000 Pentium 3 750Mhz 100gig HD 256RAM (yes i know could use more Ram).

Hs anyone seen this glare problem before?

is this present on the original disc?

certainly no burner or burning program will change the actual information on the disc, and no transcoder (like DVDshrink) will change levels.

the onnly possibility is if you're using DVDrebuilder and something wacky is going on within avisynth or a template script in rebuilder or something. that's highly unlikely if you haven't changed anything since install, and i'm not sure you're even using this program in the first place...

perhaps you should adjust the picture settings in your DVD player (it's not the TV after all :)).

Hi!The on screen image always seems to
have an area where the the light is of a higher intesity than in the rest of the imagethis is the image that is on TV after the burn, the image i see on the computer monitor shows non of thisThen it would seem that there is nothing wrong with the burned DVDs - and the problem is either the TV (wait 'til your wife goes out shopping, then try to adjust or the standalone DVD player...

[cigarband]

no, this is not on the original disc, commercial disc's look
just fine.

Checked my DVD player, there's no provision to make adjustments on it , just the usual on/off eject play stop etc..

...and i'm not using DVD rebuilder or avisynth.

[cigarband]

Glad you don't think my burner is bad, i'm wondering if there
isn't some kind of automatic adjustment signal that manufactured
discs put out that a home-made one wouldn't have?

So basically you're saying this (from what i've understood) :

- Original DVD on TV: ok
- Original DVD on PC: ok
- Copied DVD on TV: glared
- Copied DVD on PC: ok

Please correct me if I'm wrong, but ...

... there's no reason for this to happen, unless you always watch copied DVD's whith your windows open and close them to watch original DVD's ;)

only difference between a commercial disc and a burned one is CSS encryption and glass mastering (and some commercial discs aren't even CSS'd).

macrovision might be a possibility - it will have been removed on the burnt disc. perhaps the AGC in the TV is reacting positively to the macrovision signal the DVD player puts out.

again, not all commercial discs have macrovision - it's expensive and completely useless, so it only goes on if a client asks for it.

macrovision might be a possibility - it will have been removed on the burnt disc.
By default, Macrovision should have been removed - make sure you didn't uncheck this option. That's the only thing that would fit this issue.

I've just read the Macrovision article on wikipedia (http://en.wikipedia.org/wiki/Macrovision) and indeed it seems you are right ... but both AnyDVD and DVDShrink (according to the article) are supposed to remove Macrovision, which is why the problem mentionned here is really surprising imho o_O

Edit: Oh wait a minute, would you mean that the picture only looks right if macrovision is left in ? Seeing the number of DVD's he's had the problem on ... dunno what to think lol.

[HyperHacker]

Have you played commercial DVDs without Macrovision, and do they look alright? It's quite possible your TV is maladjusted (or even somehow detecting a DVD player and compensating for Macrovision it assumes will be present); Macrovision does different things on different systems, on some, the picture goes really dark, so if your TV had the brightness way up, they might look OK but discs without it would look too bright.

I assume your player is connected directly to your TV, not through a VCR or anything? Is there anything else connected to the TV?

If he had anything like a VCR in the way of the signal from his DVD player to his television, then original disks would likely look terrible.

I'm willing to bet that it's all in how his set top player handles recordable DVDs. If it's an older set, it might not know how to handle a burned disk (commercial disks are pressed, not burned). His set top might not have as sensitive a laser as his PC drives do, as well. With new DVD players rarely exceeding $50 these days (I shop at Walmart, and am not ashamed to admit it ;) ), he might profit from buying a new set top and trying that out. It might also be wise to lower his burning speed... why aren't I addressing him directly??? :)

@cigarband

Taking into consideration all of the above, would you say that your set top is an older model? Maybe even posting the model number might help. If so, the fact that it's reading the disks at all is a good sign... so try burning a few disks at around 4X, and playing those back. Sometimes you simply don't want to burn your disks at their rated speed, because you wind up with errors that your computer's drives might not necessarily be bothered by. Also, try not to multi-task (use your computer for other things) while you're burning a disk. This will free up the maximum amount of computer resources to make sure your disk gets as much attention as your system can give it. The slower burns only really take a few minutes more, so chances are by the time you refill your coffee mug, you'll be done. If that doesn't work, I'd serriously try buying a newer player.

@writersblock29: Really, it isn't any burning problem, it's something to do with the picture in itself. The data is burned properly, otherwise the picture just wouldn't show up, and he wouldn't only have a glared picture, he would also have nasty green & purple-colored macroblocks showing up (the video/data would be clearly corrupted, not just "too bright").

I like the idea of having a VCR between the DVD player and the TV though, this would be a part of the explanation :)

Sidenote: Since he probably watches TV with his, hmmm, TV! lol, the picture is more than probably correctly adjusted already (otherwise I think he will have noticed :p).

Qouted from previous post:

- Original DVD on TV: ok

- Copied DVD on TV: glared
- Copied DVD on PC: ok

This is pretty much what my understanding of the whole issue is, as well. Which is why I stated that having a VCR in between his DVD player and Television would have messed up the signal whenever he attempts to play an original DVD because the originals still contain Macrovision--while his copies do not. Thus, the copies' playback should be fine, while originals should look screwed up--exactly the opposite of the actual situation.

Qouted: "Sidenote: Since he probably watches TV with his, hmmm, TV! lol, the picture is more than probably correctly adjusted already (otherwise I think he will have noticed )."

I never hinted at the possibility of his television being out of whack. I said that his set top DVD player may not correctly play back recordable disks (some older players have issues, since they were only supposed to read DVD-ROM, pressed, disks... not burned +-R disks). Since the recorded disks *do* play (while not correctly), my suggestion was to lower his burning speed to try and eliminate burning issues as his problem: Bad burn=bad playback. Sorry if I was misunderstood! :)

[DarkZell666]

Lol, only the first block of my previous post was for you, the rest of it was pointing to what HyperHacker said, sorry if I wasn't clear enough :p

However, when burning problems arise, they severly corrupt data in general (they don't simply magically turn the contrast up =)), so imho this is out of the way from the beginning ^^

Anyhow, there's something not quite right here if you ask me, let's wait for cigarband to come back with more input on his problem :)

[writersblock29]

@DarkZell666

Gotcha! ;) And you're probably right about it not being a burning issue... kinda grabbing at straws, here. Who knows? Maybe it IS that darned window across the room from the TV! You've gotta hand it to Cigarband though; thus far, he's sure got us thinking!
