best file format for collecting clips on the PC

[ChromePlanet]

What's the best way to collect clips on your hard drive? I'm currently storing favorite TV clips in MPEG-2 video and AC3 audio in MPG files (content was extracted from a TiVo).

Will I have any problems using these files to make DVDs down the road? Should I be collecting in the VOB format instead? What programs will let me edit my MPG/AC3 files without re-encoding?

my 2C worth.. I store files in .tmf format.. you can always extract they .ty or convert to .mpg whatever and if you loose a hard drive in one of your tivos or want to put the movies on one of your other tivos the .tmfs is the best format to put back onto the tivos....
