Whenever I play back a DVD I have mad on my standalone player, (Hitachi), the video is choppy.

I used TMPGEnc to encode the video at a rate of 4750 kb/s, and authored with DVD Maestro.

On my computer the DVD plays fine. Sad

Any thoughts on this?

Probably a media issue. Some players don't like some brands / types of media. Try the disc on other players. If it plays correctly, it's definitely a media issue. In that case, try using different brands of discs.

The same discs work fine when authored at 8000 kb/s VBR. But then I can't fit a whole game on one disc. Sad

This disc was also burned at 1X.

The only other thing I did was, when I encoded it will still bigger than that which would fit on one DVD, so I used DVDShrink to compress is another 10%.

I wonder if that had anything to do with it?

I used your bitrate calculator and the size was off. I wonder what happened?

Re-compressing the data can cause some problems, especially in terms of quality. I don't see why it would make the playback choppy, but maybe DVD Shrink does something to the file structure that confuses some players.

The calculator actually leaves a security margin of about 4% (recommended by most professional authoring systems) for overhead, etc., so it's strange the data didn't fit. Did your DVD have a menu? Did you include a player on the disc? Make sure that all extras are mentioned in the "other assets" field.

Also, make sure you are using a recent version of TMPGEnc. Some older versions sometimes didn't stick to the specified bitrate (ex., you selected 8 Mb/s and it actually used 8.2 Mb/s).

Compare the size of the resulting M2V file with the size mentioned by the calculator. If they don't match, send me a message so I can try to figure out what's going on.
