We downloaded about 50 different videos all about 7 minutes long from various sites, and about 5 of them worked completely. Most of the downloaded videos play until the 5-6 minutes mark and then just stop. The picture freezes, the video looks like it has a minute or two left and the progress bar continues, but nothing plays any further. The image is frozen and there is no more sound.
I ran the logs and tried one of them again. This video stops at 6 min 10 seconds. It should go to 7:47, but the last 1min and 37 seconds are just the same frame and no sound.
