Just tried this one from an older CA hack - and it works.
This will enable VCD playback & MP3 playback, which I think just about covers the whole 9 yards with this player.

Turn player on
Push Setup on the remote
Move the cursor over the speaker setup menu but don't select it
Type 9,2,1,0 on the remote. A menu appears
Switch the support mode to ON.
Press setup
Turn the player off then on again.
eh voila

Incidentally, this also reveals a menu that will disable HDCP on the Video outs as well.

All in all, I really like this player - VFM wise, you can't go wrong!

Enjoy!
