Hi, I've looked through all of the threads to try to find an answer first. I had no problem making back ups for a while....then I thought I had no problem, until every disk began stalling, skipping, freezing at different places in disk...all coasters -even ones that worked once, but wouldn't play again -(about 50). I read advice, and got better disks (I was using Imation, then Memorex, then TDK, now I have Verbatum.) They seemed to be working, now every 2 movies or so, I get all sorts of errors...sometimes I/o and other errors during reading, lots of them near the end of burning, so I only get a partial movie. These happen with dvd x copy platinum, new and old versions, with updated shrink and decoder and I have anydvd running in the background (updated. I turn off norton anti virus and firewall etc... so I am ending up with a lot of coasters again. Also, sometimes the movies work when I check them (all they way through), but then when we go to watch them, they freeze. I have a hp media center pc m470n, fairly new...an hp dvdwriter, 53 % free space on the hard drive. I think I have followed all of the previous threads for each individual error, but nothing seems to consistantly work. Any ideas? Sorry this was so long!
