I don't know if DiVA involves quality loss. I use it to get small sized files up to TV resolution because I put my stuff on TV as well as on the internet. It looks good, and the files get much much bigger. So, I assume I'm doing the oposite of compressing (expanding?).
You did remind me that on the archive.org FAQs it does mention that you can use Cleaner to do the conversion work to. I don't own Cleaner so I didn't pursue that. --- In videoblogging@yahoogroups.com, Harold Johnson <[EMAIL PROTECTED]> wrote: > > Thanks Rob, > > Someone told me about bbDEMUX the other day (perhaps you) and I used it to > separate the MPEG2 file.
