Yep, it does not.

That's news to me, I was thinking newer version can handle the hardware
better ...

I'd rather not downgrade.

Hmmm, VDR can be viewed over the network?

Well, the situation is a little more complicated. I have home network,
my PC, wifes, one media center and one laptop. All of these have
one single OS installed and it is Gentoo. My desktop has MythTV backend
running with pcHDTV 5500. The trouble starts when something is
recording or Wife wants to watch while I'm watching or I shut down my
box. So I thought adding one master backend would solve these problems.
The only box suitable for this job is my home server, which is running
FreeBSD ... It is not very powerful, thus I got an MPEG encoder
card ... PVR-250.

Well, currently I log into server over SSH, do cat /dev/cxm0 > file.mpg
where file is created on an NFS shared volume and use mplayer to watch
it on my desktop, works fine.
I wonder if there is a way to access /dev/cxm0 over LAN (some magic
with netcat perhaps?), without logging in over SSH, so Wife could watch
it from her desktop. SSH login is a little too much for her ...

Thanks for reply, Saul :)
