[mythtv-users] Missing recordings Update

[Ray Olszewski]

Well ... Isaac is really the expert here, of course, but it appears to me 
that the problem is what I guessed at first ... that the time between 
stopping the second show and starting the third is insufficient to let the 
third show start recording.

I just set my Myth host (running latest .deb binaries, not CVS) up to test 
this sort of timing problem here, but of necessity, the test takes 2 hours 
to complete. I'll get back to the list later with its results. I did try 
something similar last week, but it involved capturing several consecutive 
shows on the **same** channel, not as demanding a task since it does not 
require that the vidcap card be reset ... just that the capture output 
switch to a new file.

Do allow for the possibility that the latency in stopping capture depends 
on the hardware. I'm using an AverTV card here, and with other capture 
software (var/avifile), I always had to leave at least a minute, better 
two, between stop and start of capture. This was partly (though I think not 
entirely)  due to the limited time resolution of crond ... I expect Myth 
uses an internal timer that is capable of timing to the second, not just 
the minute. But still, your PVR 250 and its driver may introduce latency 
that Myth does not allow for.

If I see the same problem in my test, though ... then I wonder if Myth 
needs to refine its calculations of when two captures conflict?
