I saw one of those comments, that CD's are so 20th century, but it seems like young artists are still trying to sell new vinyl records. I don't know how many small time bands I have seen recently, not only selling CD's, but records as well. I think the people writing MythTV just are not very hip.
So I should buy vinyl replacements for all my CD's so I don't have to worry about this?
What I meant by the CD's are so 20th Century comment is most people don't play the actual CD they either buy their music in digital form or if they do have a CD they rip the music from it and play the digital copy. There are many advantages to doing that like you don't have to go hunting for the physical CD to play it you just point your player of choice at the digital copy. You can have your entire music collection available and ready to play on any device you desire including all MythTV frontends, you phone, tablet, many UPnP devices etc.
I did start to look at fixing the physical CD playback in MythMusic but it turns out the main problem is lack of UDisks2 support in MythTV we only support UDisks1 which most distros no longer use. In theory QT's D-Bus support should make it easy to add UDisks2 support but in practice I couldn't get to work at all so gave up in frustration.
