I've been able to backup a number of episodic bluray discs with no issues (only issue I've ever had was with CUDA support, so that's been turned off). For some reason, all of the Sopranos Season 1 discs get stuck while trying to compress their respective 0010.m2ts files. I've tried directly from the disc and I've tried from rips (both ISO and directory based). They all have the exact same result. The compression mb/s starts slowly going down until it disappears and then it just seemingly hangs. I left it going for 24 hours once and nothing ever happened. I've tried other discs after running into this issue and they haven't had an issue. I was originally using version 8.0.8.5, but upgraded to 8.0.9.2 QT to find the same result. I've included some logs below, probably not from the same attempt, but there have been no differences in any of the discs. They all fail on the same named m2ts file. If there is anything else I can supply, please let me know. I'm running Windows 7 64 bit, 4 gigs of ram and an Intel Core 2 Quad Q9550 @ 2.83 GHz.
