Hi Aman

I reverted that commit in my source. Playback still works fine. I have 
removed the logging of every frame so I cannot see exactly how often the 
retry occurs, but it looks like they are about the same as before.

I disabled MythTV deinterlacing, and interlaced content seems to be 
fine. It looks like Nvidia Shield built in deinterlacing is working. I 
have not made the change you suggested (reading all frames before 
releasing a packet). I will make that change.
