[mythtv-users] Fixes 32 v32-Pre-3519-g0caf3ac0ec crashes when a remote Intel based front end attempts to read Live tv stream

[John]

The issue is repeatable so I will raise a bug report when I figure out 
how to get a proper backtrace.

Works on an Android 32 bit frontend.

Does not crash but playback is erratic  on local Intel 64 bit frontend

A remote  Intel 64 bit VAAPI based frontend crashes with

022-02-06 15:28:38.249116 I  TV::StartTV(): Entering main playback loop.
