I have done the card swap, no joy. I reformatted the original card, replaced the "buda" folder and put it back in the player. I then reloaded the firmware update and as I write this the player still will not play Disney discs and BBC productions. I am watching Avatar, and it will play Harry Potter. Sooooooooo, I guess I will be shopping for a new BD player and relegating the Pio to DVD/CD duties. Is there a possiblity that this player has developed a region issue.
Unless your player has had a hardware mod to make it region free for Blu-Ray (quite extensive and usually expensive) then I would suggest it is nothing to do with a region issue.
I think I have mentioned before that it is possibly a dirty lens issue and that it would be worth cleaning the lens by one method or another, it might sound coincidental but we have seen several such coincidences on this thread where unrelated problems have occurred at the same time. As vader1515 has posted (good post by the way) probably the best way to clean the lens is manually, others have used a cotton bud for this purpose probably the first damped in isprophyl alchohol and the second dry, but note this should be done with care. The other method as mentioned by others is to use a commercially available lens cleaner I believe these can be obtained in both wet and dry versions but make sure it is one intended for Blu-Ray drives and with brushes, some sold for DVD/CD lens cleaners have extended brushes and can damage a Blu-Ray drive lens mechanism.
The additional information you provide on the discs that will play really indicate to me that in all normal respects your player is OK interestingly Avatar in particular loads quite a lot of information into the BDMV cache and if you stop the disc part way through and restart it a resume play function comes up after the disc has reloaded. If that is working then I think the lens cleaning is the step to take. I did have a problem with a specific DVD in the past, that froze part way through on the 05 but played OK elsewhere, I ran a Maxell thunderon Blu-Ray cleaner in the player and since then that disc has played OK.
Going to be interesting with Skyfall, out here Monday it will be played in the main system but I will try it in the 05 and see what happens and of course report back:D.
I think b curry comment on maybe we will get a firmware update is very valid, I have mentioned this before and we will see whether Pioneer are still functioning on a proper level, there is certainly no movement on the firmware front on the European site and I believe this is where most firmware updates originate these days, even the Japanese site has updated in the past after Europe.
