Can't playback on standalone player

[sheets]

For some reason, some DVDS will only playback on my computer. I think the issue is the menu somehow is getting screwed up but I'm not sure.

My workflow is dvd-decrypter followed by DVD Shrink using the fitcd algorithm.

Any thoughts as to what could be going wrong?

P.S.

I'm using Verbatim 4x+R medium. Some disks that don't have to be shrunk seem to play fine on the standalone player so I'm thinking that it's an issue with shrinking them. I should also mention that even the ones that play on the computer seem to have weird stuff happening like the default stream that gets played back is the closing credits...

Is it just a matter of telling DVD Shrink what the main title is?
