Aspect Ratio Problems?

[goretusk]

I'm trying to backup Family Guy Season 1 Disc 1 using DVD Rebuilder and CCE 2.66 and I'm having a playback problem. The video is being stretched horizontally or squished vertically (the video is too long horizontally)...When checking the .m2v files that DVD-RB created in both the same software DVD player and in WMP I see that they are fine. I opened the first VOB of the rebuilt DVD that corresponded with the same scene as the created .m2v file in bitrate viewer and the information (minus the frame rate) was exactly the same.

This must be something happening in the rebuild process? I did Family Guy Season 2 Disc 1 without any problems...playback is fine. Any thoughts, clues, or is this a bug?

Thanks

Did you use the half-d1-extras option? Dont use it for episodic discs where episodes are in separate VTS's.

I didn't use it, I'm positive too because I checked it multiple times. Also, I noticed one other thing...for the disc that came out bad the field type is "frame" and the scan type is "zigzag"...though for the one that came out good the field type is "field" and the scan type is "alternate"...so if it is a bug in the software, that's a good starting place.

Still accepting replies to this one, heh...I have no clue what's wrong.

I noticed the same thing with the Family Guy Disc 1. DVD-RB (.51c) makes a messed out of it. For some reason it's not rebuilding the IFO files correctly which is causing the wrong aspect ratio (the vob is encoded correctly with the right aspect ratio). I used IFO edit to manually change the aspect ratio to 4:3 which fixes the aspect ratio problem. However that's not the only problem. It appears this disc is one of those hybrid disc where the episodes jumps from progressive to interlace. Rebuilder is encoding them as progressive which in the end causes interlace lines every few seconds during playback which isn't in the original disc. The proper way to handle these hybrid disc would be to either IVTC or to encode as interlace. But there's no option in rebuilder to force this.

cool, thanks for the tip...I just broke down and used dvdshrink on it...but if I ever have that issue again I'll try using IFOedit. As far as the interlacing stuff goes, are you watching the DVDs on your computer? I have a DVD player and I watch them using that so I basically just disable deinterlacing. ;)
