I am having this problem which I think might be due to outdated firmware in my JVC XV-723GD DVD player. Minority report gets blocky and freezes mid chapter 12. BTTF main menu page won't go to languages. When I click on languages it goes to bonus features, and selecting scene selections starts the movie. BTTF 2&3 always start with the commentary audio on and since you can't change audio tracks on-the-fly this is annoying. This player has never met a disc it didn't like until these two. My friend has the same exact JVC player as I have(XV-723) but his was purchased recently whereas mine is over two years old. He didn't have a problem with MR (my disc) on his player, haven't tried my BTTF on his player yet. Does anyone else have this player? How can you find out which firmware version your player has? How can you upgrade the firmware to a newer version(if it turns out I have an older version)? BTW, All of the discs I owned previous to this problem which I have re-watched since still exhibit no problems so I don't think the player is taking a crap. Any help will be greatly appreciated as always.
