By default, the ivtv drivers support up to 3 cards per system... what
did you patch exactly ?

The latest stable release of VLS is 0.5.3.

Could you send us the log and a backtrace ?

We have a streaming server running with 2 PVRs and a very good uptime.
We had some problems when using 3 PVRs in this streming server. Have you
tried with the "decoder-dev" branch of the ivtv CVS ? Did you try with
the patch developed by Jens Axboe ? What kind of device do you use as
client for the streming server ?
