First and foremost, kudos to c4e and 'support staff' for your continued great work. Thank you for sharing. Thanks much for the return of speed switching.
SL Backup Results:
All media tested - drive can't read the disc (spin-up/spin-down cycles lasting a second or so). I get this same behavior with DVD movie backups too for all tested media. The media I've tried is obviously not compatible with my drive. I have yet to witness a successful test with many different types of media on v5.x so far. All discs made (game/movie) work OK in the XB1.
