[mythtv-users] Shield fronrend and video playback times

[Greg Oliver]

I see frequent issues with time calculations on some recordings - in other
words, while the video is still playing, the progress show it at the end
already.

I watch Nova (and others) on PBS here and they all show the symptom.  I am
unsure exactly when it happens, but I have watched 3 this morning and they
all jump to the end.  If I set a bookmark, it actually sets it at the end
of the video even though there is really 20 minutes left to play.

Recorded from HDHR.  I see it on other local channels as well, but not as
frequent and I have not analysed video when it happens.

Anyone else experience this?
