(Note: this is a v3a8 bug, and I've not tried v3a10 yet, but since Dave was focussed on the tuner code, I don't think he'll have fixed it. If someone gets the chance to reproduce it before I install v3a10, please post your results here)

Using Tweak Order can confuse/crash the player:

If you have the player shuffled, and you decide you'd like more of the current artist, you hit the tweak button on the remote. If you decide you'd like lots more, you keep hitting it until it says "no match found".

At this point, if you hit track skip, it doesn't -- the screen changes to the next song (and the next song), but it never actually skips track.

You need to reboot the player to fix it.

If the position in the first track is past the end of the next track (IYSWIM), this action can also cause the player to reboot.
