I have Tron, Tron Legacy and Avatar to run through this weekend. Were any of these "known problem discs"
You will want to watch in this order. Tron classic (unless you wish to view the new before the old, I suggest the old before the new), then Tron: Legacy, then upgrade back to 1.6 for Avatar. Both Tron's play fine under 1.4, but to play Classic Tron, you will get stuck at the Disney castle, have to hit stop twice then 'Disc Menu' to get the movie going. Under 1.4 it will play without any bull. Tron: Legacy will not play running 1.6 and will get hopelessly stuck at the castle screen. Any released version of Avatar will only play on 1.5 forward. And a note you never want to run 1.5 anyway since there are some couple dozen older Fox movies that will not play on 1.5, but do on 1.6. Those will get stuck on with 'menu' on the display at some point and won't proceed. And obviously there are movies newer than Avatar that require 1.6. If you plan your viewing then you can watch with the fewest number of roll-backs and upgrades. Note that the following movies will not play under any release. There are also an undetermined number of other movies I have not tested that may or may not play that were released around the same time as these:
-Thir13en Ghosts. Only the US WB release in the combo pack with House of Wax which plays fine. The UK release loads and plays
-An American Carol
The recent movie Intruders did not load up on 1.6, but I did not try 1.4. YMMV
Note the trend with WB releases and the timeframe (look up the release dates on highdefdigest if you run into an older WB movie that won't play) There are sure to be more that don't play that no one has tried or reported yet. Also eventhough Chaplin is Lionsgate, it was mastered by WB and has the exact same problem as the other WB titles. An American Carol is mystery, but there are sure to be more Vivindi discs that don't play. They are an ultra small studio with mostly crappy not even 'B' movies so probably not an issue.
Generally if you run into a Disney BD or DVD that won't play rolling back to 1.4 will fix it. I haven't heard yet of a newer one that won't load at all unless you are in 1.6. It seems to be a common bug in the newer 1.6 code to fix older Fox titles that causes this issue. One of the PotC movies I recall the 3rd @ the worlds end would not play on 1.5 but on 1.4 and that is probably where the bug was introduced. You all can blame me for that one. Had I not found it when 1.5 released then all the other new ones would probably play and maybe PotC 3 would not. Who knows?
