[mythtv] mythtv cvs trouble?

[John Coiner]

Isaac,

I'm having trouble checking out from CVS. I waited a few minutes, and 
the same thing happened again. The error message is below.

On my machine, the recorder skips a frame every so often (once per 10 
seconds?) and as a result the output has to pause for prebuffer 
occasionally. Have you noticed this? You'd know, the prebuffering is 
really annoying. This is the next thing I'm going to work on.

First, the player should deal with a missing frame more gracefully. The 
nuppel video stream has frame numbers, which skip ahead if the recorder 
skips frames. I think the player currently ignores the frame number. I 
plan to have the player handle a sudden frame number jump by leaving the 
old frame visible during the time that would have been allocated to the 
missing frames. This will avoid the prebuffering, and better maintain 
a/v sync.

Secondly, it would be nice if the recorder didn't skip frames as often. 
I'll investigate the cause. This is the second thing to look at, b/c the 
recorder has to be skipping frames in order to test that the player 
handles them properly.

I also tried checking out MC to a fresh directory, instead of updating 
my existing directory, which made no difference.
