Just to add to the information.

The output is the stream of MPEG2 as were all the others I managed to do
in the past.

I did the debug thing as advised by the Wiki page. (I read the archives.

The first 2 steps went without errors:

[mythtv at saruman mythvideo]$ mkdir -m 0755 /tmp/fifodir_20512/

[mythtv at saruman mythvideo]$ /bin/nice -n19 mythtranscode --showprogress -p
autodetect -c 8 -s 2005-07-16-17-58-00 -f "/tmp/fifodir_20512/"
--honorcutlist 2>&1

During step 2 the CPU was quite busy for quite a while.

Step 3 dies almost instantly:

[mythtv at saruman mythvideo]$ /bin/nice -n19 ffmpeg -f rawvideo -s 720x576
-r 25.000 -i /tmp/fifodir_20512/vidout -f yuv4mpegpipe - 2> /dev/null |

Usually that means that input file is truncated and/or corrupted.
