Which builds do you use on these boards? Is it m201d for V3_1 and HD18Q for 2.0?
I use the MXQ builds for all of them
can you temporarily flash 7.0.2.2 m201d to your 2.0 board and see if playback issues are gone?
I'll give the other builds a try, but the MXQ build is the only build that controls the LED properly
EDIT: Same issue with m201d and HD18Q builds but I did just notice that the HD18Q build is incorrectly switching the video playback to 24Hz. I'll just see if thats happening with all of the builds
EDIT2: That's it! If I remove 24Hz from available refresh rates, playback is fine.
