I'm not sure about Khypermedia (bought 2 didn't play well in my stand alone so never bought anymore) but I can tell you that Memorex DVD-Rs are like a box of chocolates, You never know what your going to get. I've gone through a few dozen Memorex DVD-Rs. Bought one the first time, worked great so I went back and bought all CompUSA had (they were on sale) then after that sometimes I got pixelation sometimes they worked. After checking the discs with AdvdInfo I found out they were not all by the same manufacture. For one I would recommend that you use AdvdInfo to identify discs in question. I think it's odd that you are having problems burning them. What software are you using? Have you tried ImageTools? When I installed my A05 I couldn't get anything to burn using RecordNow Max 4.10 which I had been using with no problems with my A03. I did a test burn with ImageTools worked fine. Then I upgraded to RNM to 4.5 and it worked fine. So try ImageTools (you can have it run a test so you don't waste a disc) if it works fine then fine out what software (and version) your friend uses.
