I've been running the 23-12-2016 build for a few days now without major problems. Even VC-1 plays fine, even though I cannot test it thoroughly because of limited number of VC-1 videos in my library.
There is one peculiar problem with .srt subtitles though. It is something similar to the bug reported in posts #328 and #329. These subtitles sometimes appear garbled, with bits of the letters missing. It is not a regular phenomenon, the same subtitle that played fine one day, it is unreadable the next day. Also it doesn't happen in the same degree. Sometimes the subtitles are just rough around the edges and other times, as I said, they're unreadable.
This problem appears mostly with BBC iPlayer downloads (720p, 50fps H264 files) and only with HW acceleration enabled.
Here is a log: R1eMASm8
This log is from a session with normal more or less subtitles. Unfortunately, I didn't keep a log from a session with unreadable subtitles.
Any insight on this?
