do ps3's support xvid?
For playing them on the PS3 - DVD Shrink. Set the output as 'file' instead of image. In the options, set it to NOT break up the files into 1GB chunks. Then rip. Depending on how you have authored the 'disc' you may well end if with 3 or more VOB files. Look for the biggest one, and that will be the main feature in one *.vob
Copy the vob to the PS3. Watch it.
