Nice to see you are still around, despite as I believe you now have Oppo player(s).
Thanks for your reply but maybe I did not make myself clear, it was the BDMV data I was referring to and I perhaps should not have called it memory and been more specific, and per the manual, as BDMV data.I found a while ago that if the BDMV data is not erased (particularly after playing Avatar and pausing or ejecting it a couple of times, like when checking the load times) the player becomes very slow to eject and load the next disc and I am talking several minutes here around 5 to 8mins. Clearing the BDMV data resolved that for me
bringing the player back to it's normal eject and slightly sluggish load times. The two BD discs involved in this case were Avatar and 2012
The manual suggests clearing this regularly but Adrian457 may well be right in that it is better to clear it after every movie (I would suggest only BluRay movies) I have started that practice now having experienced the above minor problem, which I probably aggravated anyway, it is the only problem I have had with this player apart from slightly dirty new straight out of the package BD discs requiring a blow off with compressed air, and I have not had that for a while now.
My point here is if my experience above is correct which I think it is because I can repeat it, then the side effects of a faulty BDMV memory SD Card could perhaps cause all sorts of problems.
My interest was in particular if the 2Gb SD card worked as I am more than capable of removing a panel or two and circuit boards if necessary to replace it if it ever becomes necessary. It may also be of benefit to some other owners with apparently irrational behavior from their prized 51/05. The reason for the bold text is to highlight to other maybe not so experienced owners my experience and the apparent cause and cure.
Thanks to Adrian457 for providing the information requested
Best wishes, Rick
