V:Port problems - rewinding music etc

At the weekend I flew on a 346 and a 744 ( Both V:Port ) and found the following problem - completely impossible to 'rewind' on either the music channels ( VFM for example ) or any albums, and the time counter keeps on going up while trying to rewind..... Has anyone else seen this problem or is flying soon and wants to check it out? 
My other glitch list....
1) 'Virgin Web' or whatever it is ( Web site / intranet ). Has always come up with 'Sorry. Not available.' or similar!
2) When playing music and the system moves to the next track, there's a long delay and the counter doesn't reset to zero. In fact, the counter is normally way out.
3) i:map can sometimes be rather off.... Odyssey is normally spot on!
Otherwise it's fabulous and knocks everything else into a cocked hat.
