Hard to believe that. In any case if you compress to MPEG in realtime you'll get CBR and that does not make the optimal usage of bandwidth. And besides, since you are obviously planning to make DVDs, you'll have to set bitrate lower than 9.8 Mb/s total, including audio. I have not yet heard of the MPEG2 codec that can compress with good quality using CBR at that bitrate in realtime. I've seen that HW codecs mostly use around 12, 15 or even 24 Mb/s for better qaulity, that is too much for DVD, so you'll have to recompress to VBR later anyway. Same applies if you use SW codec, probably even worse since processor is also doing other things beside compression.

Tmpgenc DVD Author is very good at adding chapters and easy to use. DVD Lab has auto detection, bit it's chaptering sucks, they're always a second or so off, according to my experience. Haven't tried Scenarist yet.
