I have the same problem.  HW is Leadtek WinFast DTV Dongle Gold running
on Ubuntu 10.10 and 2.6.35-27.  The tuners used to be quite reliable, so
something has changed.  The tuners do run ok for a random amount of time
(up to 24 hours), but then once the error messages below turn up in
syslog the tuners will not work again without being unplugged and
replugged.  The issue occurs on first tuning the tuner to record a
programme (via MythTV).  This suggests to me that the issue is perhaps
being caused by a poor signal, but the driver is not then reacting to
that error correctly, which leaves the tuner in a state which it is
unable to recover from.  Just conjecture, but I am hoping this helps.
Below is an extract of syslog with the relevant messages (these are
repeated many multiples of times).
