have you tried playing them back on another player? Do you need a Windows computer or do these programs work with a Mac?
Adventures In Modern Ripping
Well it all started when trying to rip three DVD-A discs I have, namely Frank Zappa - Halloween, UFO - Lights Out and Neil Young - American Stars 'N Bars. They don't have stereo tracks or none that I could find.
Ripping is really easy now with DVD Audio Extractor, which also does Blu-Ray audio and Sonore which does SACDs.
So I ripped these discs in their MLP 6 CH format and to my surprise I was able to play them back on my Aurender's N20 SSD.
The SQ is just unbelievable, as good or better than SACDs.
Most DVD-A discs have stereo or 5.1 tracks, in most cases ripping the 5.1 track will be best, though there are some exceptions. MLP encoded discs are the best.
Rip to 6 ch single output.
The DVD-A 5.1 of Yes- Fragile is just outstanding and trumps the SACD but Fleetwood Mac's Rumours DVD-A is better in stereo.
Anyway check it out and ask me if you get stuck.
