I'm not an expert on AnyDVDHD logfiles but your log files show the 3D version also is not a java menu version. I.E. no files the Java folder. And your 3D version does not have that common 120.mpls playlist file associated with the menu with other disks you are having problems with. So it is different in that respect.
All the other disks you are having problems with have the same 120.mpls playlist that starts the menu which is where you are seeing the failure. That memory thing with "start from last.." is due to that everything works up until this weird 120.mpls based menu loads.
It still looks like a marginal performance problem with your player with a marginally compliant disk format. Also, if you are having problem with the 3D version versus the 2D version presents a whole other possible source of problems besides just the disk.
Thanks for that Roycal. The only disc I noted a difference between the 3D and 2D versions was Jack the Giant Slayer - all other Warner discs failed to load the top menu regardless?????
In any case, all problems have disappeared now and Warner discs are working fine. I found while reading through the service manual that there is a "BD History" which is retained in the unit's memory. One needs to enter a service routine menu in order to clear that and I suspect it may have contributed to the problem (will have to wait until the problem happens again, if ever, to try the service routine for clearing the disc history).
In any case, a really strange issue and now that it's gone, we may never know what caused it. I will be on guard for it again and note what conditions lead up to it.
I received the $25 "for parts" BDT100 that I ordered through eBay. It had a "locked tray" and I was expecting a jelly sandwich or something in the tray, but it was just one of the hidden menus which locks the tray and a bit of punch and peck on the remote restored full functions, so I'll keep it as a spare. I have no idea why Panasonic would put a tray lock in the hidden menu or what it would be used for, but someone found it and activated it. A sticker on the top looked like a school issue so that says a lot for how someone could have gotten into the hidden menu and locked the tray to begin with.
