Mmh, I'm extremely surprised that this issue haven't been reported before.
After testing many many builds I decided to make a drastic build switch and OE 4.2.1 has no display dimming issues :/
I can't remember when I started to use sync to display option and since only my kids are watching DVDs I haven't noticed the issue myself until yesterday. My movies are mkv only.

Can anyone suggests a build to try? My testing motivation is fading away

Well, the oldest build from this thread (#1215) and the oldest build from the last thread (#0415b) would be a couple of points in the sand.

Thanks, I gave #1215 a try but my wifi dongle doesn't work with this build. The bad thing is that I need to remove the TV from the wall to reach the rpi so I can connect a cable

I will continue the testing tomorrow.

Here's a list of builds I have been trying on my Pi B+

Code:

#0131 > #0220  has the same issue.
#0130 - dim
#0120 - dim
#0110 - dim
#0101 - dim
#1215 - dim
#0415b - wlan0 eth0 not working.
OE 5.0.1 - dim
OE 5.0.0 - dim
OE 4.97.x - dim
OE 4.95.1 - dim
OE 4.2.1 - OK

#0415b was the last build that I tried. I couldn't get the network to work so I gave up the testing (since I'm the only one reporting this issue...)

Sorry for not being able to find the exact build. I don't expect you guys to find the cause for the issue I'm experiencing, I just wanted to let you know the results.

BTW, I tried to play a movie with flac (Lossless) audio on both Pi b+ and Pi2 B. The playback was really sluggish and audio was several seconds ahead. I tried all possible settings. OMXPlayer hardware support made it better but not enough to make it watchable.
Doesn't the DVDPlayer/OMXPlayer support flac?
