I have been having plextor 716a drive. On some DVD’s the disk will pixelate and freeze around 40 mins into the disk. Not sure why it is happening so I turned to this forum. I’m also having simular problems on my other DVD Writer (its on a different computer) and its a sony. I just replaced the IDE cable on the Plextor drive to see if that would fix it, but no luck with that. I use the combo of Any DVD/Clone DVD2 for my writing.
I’m using FujiFilm media from Japan (which shows it is 8x Taiyo Yuden media). And I also have the newest firmware on the Plextor 716a too.
