When repeated pictures occur it allows the video to catch up but in your video it has some long periods where there are no repeated pictures and when the video gets far enough behind it drops frames to catch up. If your display's refreshrate is higher than the frame rate then it shouldn't need to drop frames but occasionally extended the trigger. Your latest log with DRM indicate that the most recent patch is working correctly.

Thanks. I'll take a look into the X display frequency tomorrow.
Thanks for your patches, I'm glad I could help test things out. I
have watched a few other shows with no problems as well. I'm hopeful
this patch can go into upstream. If you create a ticket, please post
the number here, and I'll keep an eye on it.
