I've been burning DVDs using a SONY VAIO model PCV-RZ24G, NERO and DVD shrink. I've had very few problems using Verbatim DVD+R. I started trying Verbatim DVD-R to play on my TV/DVD combo. After encoding with DVD shrink, I put the DVD-R in and it looks like it's going to burn, then fails. I also tried Memorex DVD-R with the same result. After the DVD-R failed both times, I tried it a third time using DVD+R and it burns with no problem. I also tried to copy my DVD+R movie to a DVD-R using NERO and it also failed that way. Any ideas? Thanks for any help.
