Comment:

 Hoelli, thanks for the info. It's not really a MythTV issue so I'm closing
 the ticket.

 But for the original reporter, I did some more research on this. It looks
 like if you downgrade the kernel to 2.5.11, or apply the patch to a later
 kernel you have a good chance of squashing this problem. Changing the PCI
 slot has also been reported to work.

 The problem with the driver appears to be triggered by the timing of
 tuning commands, which may explain why 0.18 would work when 0.19 does not.
 In svn head, you can change tuning slowdown pause in the "Recording
 Options" dialog for the card, plugging random numbers into this config
 option can let you work around these types of problems in the driver.

 I've heard from the DVB driver folks that these types of problems are
 often due to reversed engineered drivers where the required sleep after
 each type of i2c command is unknown, and the driver devs use too small a
 value.
