I have solved the problem of the player locking by updating it and also Direct X. The main improvement however is switching to WINDVD. However, even though the windvd panel is saying S/PDIF on it, there's no signal coming through to the Amp. All my connectors are ok, as I've check using it with my old DVD player and the cable and amp are working ok. Could it be the fact that it's using the S/PDIF out on the All-in-wonder? Has anyone come across problems like this before? Please help, it's no use having a 7.5 foot screen and only Pro logic!
