Youll find that you will achieve the same result by pausing for 5-10s or
rewind by 10s..

If you look into the log, you'll findq heaps of log that it's waiting for
new data to come. For some reasons, between 0.24 and 0.25 an issue was
introduced where liveTV starts way too close to live streaming and that
cause buffering issue.

I'm fairly certain that the fix you are seeing, switching deinterlacers
on/off/on is only slightly pausing playback just enough to solve the
problem describe above
