Last night after talking to the Samsung 'Help' chat person (who was no help). I figured out how to downgrade the firmware even though that was deemed to be impossible by Samsung.
First I with the unit on and no disc, I held down teh FF for 5 seconds until teh language menu shows up. Then hit 1. Then I put a USB thumb drive with the 2.07 firmware in it in the player. (I got the firmware here http://findfiles.com/list.php?string=BEv2.07_100315_BDP3600_XAA.zip&size=76068681&db=Mirrors ). It ran through the install process and then all the discs that the 2.09 firmware killed started working just fine. Hope this help others and prevents you from having to send your player in for a $150 service that appears to be unneeded. This was on a BD-P3600.
as with everybody else, i can't play avchd dvds since upgrading to the 2.09 firmware. however, i'm also having problems with mkv playback (at least when playing them off a dvd+r dl -- i haven't tried usb or network play)
- most problematic is that large mkv files are being reported by the system as only being 4.0gb. when playing, the total length/time is correct, but playback cuts off early (about halfway through for an 8gb file)
- pause lasts for a relatively short amount of time, after which the player stops playback and goes back to the menu...
- ...which wouldn't be a huge problem, except that rewind and fast forward don't work at all, so you can't get to where you left off watching
the second two problems suck, but i can deal with them. the first makes a bunch of my files useless, as does that whole avchd thing.
is anyone else having these problems? has anyone else figured out a way to rollback to 2.08?
