After installing update 4.30, Blu-Ray movie discs do not load. The drive clicks and spins, and then makes the "ka-thunk" sound as if it's reloading the disc, but then the movie doesn't show up on the XMB. DVDs, CDs, and Blu-Ray game discs all seem to work normally. Is it possible that the firmware update has a bug? Does anyone else seem to have this problem?
(I've tried re-installing the 4.30 update using a memory stick, and using Safe Mode Option 3 to restore files, and all the suggested changes to BD play options, and even chatted with Tech Support, but the problem remains.)
