First, what I am using. DVD Shrink and Nero(latest version) for backups over 4gb (Fat32 thing) and DVD shrink and Decrypter for files under 4gb. My system: P4 2.4 512 ram XP 2 40 gb HD Lite on 812s DVD burner. I spent weeks reading posts on this board and reading guides, until I thought I was ready to backup my daughters Nemo movie. (You know how 4 year old kids treat movies) Per many coaser threads, I opted to practice on nice new Memorex DVD+RW's. The first couple tries bombed. So I erased and tried again. Finally, my first successful burn. I ran right out and threw the disk into my stand alone RCA player. The +RW worked great! My kids watched thier fully backed up copy of nemo. +RW's cost a small fortune, so per this board I set out to find some Ritek GO4's -R's. So I run across this real good deal on NewEgg, 50 Riteks for $39.99. With over 200 positive reviews, I figured I couldn't go wrong. After 3 days the Fed X guy shows up with my disks. first thing I do is check in DVDinfo to see if these are really Ritek G04's. Yup, genuine article. Anyway, with the Nemo image still on my hard drive I burn to these new Ritek's. After it was done, I called the kids in and shoved Nemo into the standalone RCA drive. I worked great, or so I thought. About 45 minutes into the movie, I started to see squares. Then the squares got worse, after a few more minutes the screen started to freeze. The next day I put this movie in the standalone RCA player again and fast forewarded to the area of the movie that was acting goofy. To my suprise it looked great, the same exact places that yesterday looked screwy, looked fine today. So I played the movie longer, and again after about 45 minutes it started to act up again. I've made several backups since then. Full backup , movie only back up, and different combos of Shrink, Nero and Decrypter. The goof ups don't happen in the same place everytime,and if you shut the movie off and come back to it a couple hours later, it works fine, so I think bad media is is out. I was wondering if my standalone RCA player could be getting hot and maybe the lazer is having trouble focusing on the darker Ritek disks. Anyone ever heard of this type of problem?
