This is what I found confusing, according to the manual:
Audio Recording Format:
DVD+VR (hq, sp, ep, slp): Dolby Digital 2-channel
VCD/SVCD: MPEG1 layer 2
I suppose it doesn't matter too much because the resulting playback sounds good in Pro-Logic II. I'm using it mainly to copy shows that I've saved to the hard drive on my HD cable box (which I haven't even tried yet). Some shows are saved in 1080i and I don't know how those will record, either. I suppose it'll either be converted to 480p or I'll get no video at all.
The other thing I'll do is copy some dvd's and vhs to play on my tv/dvd combo when camping. I don't want to take a good dvd along.
Maybe I should get a dvd burner for my computer. I wonder if there's a macrovision hack for those lite-on models. If I copied the dvd's that way, at least I'd have the menu options.
