another bug, i think this one (2nd below) already known? let me make a list of what i've found in 2 days..
major issues:
1) fast forward on video streams not useable - gets stuck buffering forever, sometimes playing tiny bits. can press stop to exit. streams play ok if you leave them.
1b) "resume from (time)" option doesn't work
2) after finishing a video stream, seems to hang totally? can't press stop, have to restart xbox.
minor issues:
1) radio cache size (4096, xbmc unknown default?) too large
2) there's always a buffering delay soon after opening video streams.. maybe video needs some prebuffering.
3) not sure caching is working right - takes a long time to load items lists. i thought it was thumbnails but even with them off its still slow. maybe if you could cache all the lists for a sensible amount of time (1 hour?) this would hugely improve menu navigation!
4) cosmetic: displays 9of10, 10of10, then 11of10, 12of10 items on some lists
any others?
