So i've no idea what i've done, but here are the symptoms.

Player boots ok, and seem to play fine.
BUT ONLY WITHIN ONE SONG.

If you try to move to the next or previous song, the play just locks up. I'm also getting some random reboots.

Initially I got this after editing the config.ini for some IR Translate codes but surely that can't be it ?

I have tried flashing with 2.00 but this didn't make any difference and i've also taken the entire IR Translate section out of the config.ini

I can sync as long as the player is paused or in standby, but if the player is playing, syncing stops or fails.

edit : More testing ! .. definately the player locks up either when you forward to the next song, or it gets to the end of the current song. It is like as though it can't find the next song ? If you reboot the player it boots to the next song you tried to access. Bizarre !!

Any advise very welcome !!!

Thanks
