if you use the search feature to "insert" (i didnt try any other mode yet, but i'm guessing the same), then you skip forward twice, to the song AFTER your inserted song... and then attempt to do a rewind into the end of the inserted song... it completely skips it and goes to the previous.

I just attempted to reproduce this on Beta 13 and was unable to do so. It worked as expected rather than the way you described. I inserted a song, skipped forward twice past the inserted song, then used rewind. It rewound into the inserted song just fine.

Is it possible that in your case, the inserted song had incorrect VBR headers?

if you're in a started car, and you decide to put the empeg on standby. and then immediately, you stop the car. if you restart your car before the blinking light goes off, empeg starts, but w/ no sound. if i had to guess, the amp didnt turn on. quick standby and on fixed it.

This was something I knew about during Beta 11, and in fact the amplifier is on so that's not the problem. The player's "mute" state became toggled incorrectly. You could press the "pause" button and you would hear a brief burst of music. Pressing Pause enough times quickly would fix the problem (based on another report I read).

However, since beta 13 I have been unable to reproduce this problem and it was marked as "fixed-works for me" in the internal bug database since the guys in Cambridge couldn't reproduce it either.

Are you saying that you can still reproduce it with Beta 13? Or were you using beta 11 for both of these bugs?
