There is hope - I have 3 of them working perfectly on my server/backend. I
suspect the main difference I have, though, is near perfect signal quality -
very low or non-existent error rates.

just fine. It's just mythtv that seems to have the problem. I guess it's
possible that PCI >latencies might need looking at - next on my list - but
I'm doubtful that is the problem in this case.
I still get a couple of continuity errors when changing channel - typically
in the first second or so after the change. I assume this is just the signal
'settling down' (or something equally technical!). Do the errors actually
persist for more than a few seconds?
Have you tried xine (with dvb compiled in)? - this will give you the chance
to change channels/tune etc with another app and see if you have the same
On the latency front, all of my cards report a setting of 128.

I'm currently using 2.4.21 and did get an experimental gentoo install
working on 2.6. There were however problems with one of the dvb frontends in
2.6 - for some reason it is specifically excluded from the kernel config.
I'd suggest sticking with 2.4.25 - your problems are probably elsewhere.
