Since upgrading to Myth 0.25.2 I've been having problem with channel
switching on my PVR350.  I have two tuners one PVR350, and one HDHomerun.
Tuning problems are mainly with the PVR350.

I am experiencing long delays when switching to, or changing channels on
the PVR350.  At times I also get a flashing or pixelated line across the
top of the screen.  If I exit and re-tune the same channel it's usually
gone.  I also get recordings that are the same way, so that eliminates a
video driver issue.

When it does work after a channel change it takes up to 20 sec before it
actually displays the video on the new channel ( while waiting it shows a
still shot of the previous channel but I can hear sound from the new

If it doesn't work I get an "Error opening jump program file buffer" and am
returned back to the menu. which happens 50% of the time.  Then I can't use
the card without rebooting.

If I look at the backend status it says that it's watching live TV on the
channel and tuner I tried to tune or change to.

Has anyone else seen this, or have a fix?
