Yeah, I've been trying to burn a bunch of kid's shows for my nephew (I hate Dora the Explorer with every fiber of my being), and I noticed that PowerISO doesn't recognize my memorex blank DVDs. I tried several as well. Is that a quirk of the program or a sign that my DVD drive is going to kick the bucket? I think the drive is an HP 300c. If it is the software, then do you guys recommend anything I can try? I can't really find one that lists burning .daa files as a feature. Or I'm blind. Or both.
