since my last posting i've noticed another issue probably related to this thread on my Ipod Video 80GB:
when a track is playling (by resume or manual start of playback) during the inicial scan starting another track from any saved playlist (with about 10-20 track entries on them) renders the player frozen for about 1-2 minutes:
during this time pressing "menu" or the scrollwheel do not work, the inicially started track continues to play but the next one started from a playlist begins to play only after about 1-2 minutes (when the scan is finished)
