Now I can provide some feedback!
First of all, thanks again for all the help getting this working. MC has improved on my Tivo experience. More on that later.
I think I found a bug. When playing the album "Hazards of Love" by The Decemberists over the Tivo via the MC server, the songs don't play in the correct order! Most of them do, but a few are out of place. I downloaded the album from Amazon.com, and the tags seem correct. Playing the album through JRiver MC on the PC works correctly, and playing the same album via Tivo's native server also works correctly. Something must be tripping JRiver up. I haven't noticed this with any other albums yet. Can anyone replicate this? I am playing this by doing an artist search, then clicking play when the album folder is highlighted. Is there a workaround? It's certainly an unusual issue!
I originally found JRiver MC when trying to find an alternative to Tivo's native server. My Tivo exhibits two behaviors that are very frustrating:
1. When pausing a song during play, resuming would sometimes cause the song to only play for about 10 seconds or so. After that, the next song would start playing. That song would only play for 10 seconds, then we were off to the next song... and so on until the end of the album. The JRiver server hasn't done this yet, so this is a big improvement!
2. This problem seems to exist even when I use the JRiver MC server, and it existed on Tivo's server too.... when pausing a song during play, resuming would often (almost always) cause the song to finish, but then the next song wouldn't play. It's as if by pausing, the player forgets there are other songs in the album. Manually advancing (channel up) plays the next song, but again it stops after that one. The only solution seems to be to replay the current song, then fast forward to the end. When it pauses at the end of the track, I need to fast forward again to get it working.
This is still an annoyance, since if I need to pause the music for any reason, such as a phone call, it requires a complex manual intervention to get the album or playlist going again. If I'm off doing something and someone else must do this, forget it! Does anyone have any ideas if this can be fixed? Is it a problem that only Tivo can address?
Thanks.
