can anyone point me to information on the difference between these two types of mpeg2?

is one more compressed than the other? I need the facts! :O

The difference is only in multiplexing. Mpeg-2 outputs mpeg file with both audio and video, while mpeg2-dvd outputs m2v and wav/aiff streams. You can set quality and size to your liking in both, just remember that DVD player will only read up to 8 Mbps of video.

Thanks! and I didn't know that DVD players only read up to 8Mbps - good to know!

No problem. Here's a good brief explanation of DVD data rates:
