Installed the 2.0b3 update, marked a file for attention. File wouldn't play back properly after that point: lots of static, very nerve-wracking. Thought it might be my car's sound system, switched to another track, music was fine. Hooked up the empeg -- er, sorry, Rio Car, whatever -- at home, played the marked track, same static, other tracks fine. Removed the track from the unit, ripped it again and uploaded it to the unit, plays fine (occasional skipping since 2.0b3 install notwithstanding). Played this track countless times before the 2.0b3 upgrade, never had a problem.
