I've got an odd one (at least I couldn't find a similar report by searching). I've been using AnyDVD for a couple of weeks now, and it works great for playing originals and when making backups. But when I try to play a backup while AnyDVD is enabled, I get an big error dialog saying it can't read the disc, the disc may be dirty, etc.. I can't even browse the contents in Windows Explorer - it just acts as if I put a bad disc in.
If I disable AnyDVD, the discs play fine. I have tested this behavior on a number of my computers, and it has done this through the past few versions (the last month or so).
These backups were all made with the latest DVD Shrink, DVD2One or Nero, written by a variety of drives including a Pioneer 108 and a NEC 2510 and 3520, on Ritek 8x DVD+R discs, booktype set to DVD-ROM. They work great everywhere except on a computer with AnyDVD enabled.
Any clues? It wouldn't be so annoying if it wasn't killing the WAF on my HTPC.
