Essentially the same thing I did, though I ended up booting into runlevel 5 and using gdm's autologin and so on from there. Still, if it's a system that's basically dedicated to myth, you shouldn't be running into that sort of trouble with your hardware.<BR>

Then it sounds like your best course of action would be to try to eliminate as much signal noise as possible in whatever ways you can. (Building management, cable company, etc..) <BR>

Can't offer much help here, since the card I use seems to work great, and I haven't had any need to try any others. (Though I've got a PVR-250 on my shopping list. ;-) <BR>

I <I>can</I> say that I was really disappointed with the SAAxxxx TV-<I>encoding</I> chipset though. Don't have the exact chipset handy, but I could look it up if anyone wanted to know.<BR>

on both the Leadtek and the Pinnacle cards the coax

connects to the tuner (it's a slide-on connector,

this might have something to do with it, but I don't
know how many cards actually are like this.</I></FONT></PRE>

My WinTV has the whole tuner unit, including the connectors, as part of a shielded housing built onto the card. Though I can see the setup you have possibly adding some more noise, if your picture isn't significantly noisier since you added your myth setup, I doubt you'd solve your frameloss problems with a different connector housing design or a different hookup configuration. :-(<BR>

at the console, do you see any "rebuffering (X,Y)"
messages (where X and Y are numbers)? Depending on
the channel I'm watching, I see these messages
anywhere from every 10 seconds to every 10 minutes
(sometimes I get a few of them every 10 seconds and
then they go away for 5-10 minutes). In order to keep
track of the times, I modified the RingBuffer.cpp file
to print out the date/time.</I></FONT></PRE>

Yes, I've seen them, though by the looks of the recent console output on my two frontends, it only happens when I go into cutlist edit mode. It might be happening on my remote frontend during regular playback too, I'm not sure. I'll keep my eye on it.<BR>
