I have a bunch of captured MPEG-2 files on my PC which I've used to create SVCDs. I'd like to delete them but still have a copy of an MPEG file if I ever need to edit it again. Besides the bitrate difference, has anyone ever had problems using the MPEG file on the SVCD for editing/viewing on the PC? How about the .DAT file on VCDs? Just curious if I can rely on these MPEGs later on my VCDs/SVCDs. If so, it wouldn't make sense for me to backup the original MPEGs. Thanks.
