James post lead me to investigate this further and search the ivtv-devel list 
as this ivtv-users is not.  The reason I asked about record-v4l2.pl was that I 
can start and stop mplayer /dev/video0 as often as I care to and the driver 
never hangs, but I could only run record-v4l2.pl once.

If I tried to run it twice I had to reboot, as /dev/video0 remained opened by a 
zombie perl/record-v4l2.pl process that couldn't be killed.   If I run modprobe 
-r ivtv immediately after record-v4l2.pl everything seemed to work fine, though.

Under syslog some suspicious warning messages showed up:

  ivtv0 warning: ENC: EOS interrupt not received! stopping anyway.

  ivtv0 warning: ENC: waited 1000 ms.

In the devel list reasons for this run from bad VIA chipsets to bad encoder 
firmware. I have ATrpms ivtv stuff and thus I've been loading the 0x02040024 
encoder version that Axel supplies and generates the "firmware can be buggy" 
warning.  I thus downloaded the latest firmware version 0x02050032, and my 
problem went away. The only syslog warning now reads:

  ivtv0 warning: ENC: EOS took 196 ms to occur

Back to regular programming.
