I did another one.

terminal 1:

[mythtv at saruman mythvideo]$ mkdir -m 0755 /tmp/fifodir_23962/
[mythtv at saruman mythvideo]$ /bin/nice -n19 mythtranscode --showprogress -p
autodetect -c 5 -s 2005-06-05-22-00-00 -f "/tmp/fifodir_23962/"
--honorcutlist 2>&1

Waited some seconds and went to terminal 2:

[mythtv at saruman mythvideo]$ /bin/nice -n19 ffmpeg -f rawvideo -s 720x576

The pipes are there:

[mythtv at saruman mythvideo]$ ls -la /tmp/fifodir_23962/
total 24
drwxr-xr-x   2 mythtv mythtv 4096 Jul 23 08:29 .
drwxrwxrwt  17 root   root   4096 Jul 23 08:34 ..

prw-r--r--   1 mythtv mythtv    0 Jul 23 08:33 vidout

But how do I determine wether or not something is inside these named pipes
(fifos)? I did not update ffmpeg untill I noticed this problem was not
going away. But I did upgrade the mythtv packages as I kept up with ATRPMS

So I suspect mythtranscode to be the problem but would like to determine
it some way by means of inspecting the results of mythtranscode.
