I have a Pioneer DV 545 that has a sprinter multi region mod chip. I bought it from Home Cinema Heaven. I watched the Beatles Anthology last night which is region 0. After watching I left the player on for around 2 hours and it was on the Beatles menu screen. Today, it won't load any discs. I have tried various region 2's, region 1's and region 0's. The sprinter chip normally auto-detects differant regions. I have also tried manually changing the regions. Has anyone got any idea's what could be wrong with it ? Thanks in advance. It play's Cd's no problem but it appear's it can't load the menu screen for DVD's ??
