Hello,
I have been running mythtv since about 2004 quite happily but I am now
struggling with digital video content.
The problem I am having is with different HD content from my HDHomerun.
For example, I have some HD channels that appear to be progressive
scan @60 frames that play beautifully with no stuttering. Others though
that appear to be SD content, stutter terribly. In the playback logs I
see messages like:
doubling video frame interval to slow down.
2007-12-09 12:32:58.926 NVP: Video is 4.31844 frames ahead of audio,
doubling video frame interval to slow down.
Here is the full log: http://www.blandford.net/mythtv/playback.log
In the logs, you can see depending on the channel, some times it is 4-5
frames and other times is is 30 frames per second.
I currently have a backend with a pvr-500 and a HDHomerun.
I also have multiple frontends, each with nvidia 6150 or 6200 cards.
The displays are using the nvidia selection of 1280x720_60 connected via
DVI to a TV or flat screen monitor. I am running the nvidia 110.14.11
driver since anything newer causes problems.
I am running trunk 14921 with the cpu++ profile, but I have had this
problem since I purchased the HDHomerun. Initially I was running .20
with bob deinterlace.
I am guessing there is just a setting that I need to configure, but I
really just don't understand what needs to be done.
I am looking for some guidance on how to tackle this problem.
Thanks,
Michael
