Re: capture from DVD

If you're putting 6 hr. of surveillance on a standard DVD, you're kicking the cr*p out of the quality of your source video.
Even if it's only 2 hr. that you're transferring, it's still taking a quality hit and you don't want to do that with surveillance video.
You'd be much better off finding a minDV camcorder that has the pass-through feature and capturing it that way.
This way, the quality loss will be minimal.
