WMV vob mpg avi .dat (video cd) files are basic fromats that most dvd players will play
these are the basics...so they will surely work...i have not included anything like HD etc
Could you provide some specs on your TV (HD?) and USB drive (size?). You didn't really specify if you want a balance of quality and quantity, since the higher quality, the less quantity of movies you can have on a single USB drive.
For the best loss-less quality, simply burn the TS or VOB folders after you rip the DVD. When you burn these you don't loose any quality. You would use a program such as ImgBurn or Cheetah DVD Burner (I think it can burn to a USB) to burn the VIDEO_TS folder. However, since these can be tricky to burn for the first time, the next best are probably an uncompressed AVI (but it can be huge) and MPEG-2 (nice balance)
