Yes. As long as you are using the profile for your recording, I don't think it 
matters which one you use. Default is easiest, since that what it uses by, 
um, default. :)

Yes, assuming whatever signal you are recording from has more than 352 
vertical lines of resolution. (Analog cable has less than 300.) But yes, the 
potential quality is certainly higher with 720. Actual quality depends a lot 
on the source quality. My best advice is to compare for yourself.

That's fine. In fact, very close to my own settings.

Sampling rate should read 48000Hz, I assume 4800 is a typo. Layer II is fine 
in my experience, I've never had it fail to play in a DVD player. There's an 
assertion on the list recently that it's only compliant on a DVD as a 
subchannel with a primary channel of PCM or AC3. I haven't researched this 
yet, all I can tell you is that I have made many DVDs with only MP2 audio and 
haven't had problems. I haven't seen Layer I used. We all know Layer III, 
which isn't supported on DVD, as the ubiquitous MP3.

Looks fine to me. You have fairly common midrange values set for video and 
audio bitrates. You can adjust them for more or less recording time per DVD, 
but these are perfectly sane for general use, IMHO.
