You'll have to decide if you will forgo the 200 MB per minute to get more minutes. I usually go for 2 hours but if you tinker with the quality you can hit 6 hours of just better than VHS tape.
Ulead.com has demos so you can try before you buy.
I also CDBURNERXP to record on dvd media, but that while that answers your question, the question was not very complete.
how many miniDV or Dig8 minutes can you fit on a 4.7G DVD if it is captured at about 200 MB/minute? What program do you recommend for burning the DVD?
