Hi,
    I've just applied the patch and compiled the drivers. I haven't tested
actual tuning, since I'm not in front of my computer now, but this is awaken
and idle so MythTV is  currently simply scanning EIT data. So well, the
following messages has started appearing on my mythbackend.log:

The error about "offset>181 etc..." is usually due to the card receiving
corrupt data, and usually causes MySQL table corruption that must be fixed
using "myisamchk". I'm pretty sure this wasn't appearing these past days,
and today we are in a very good weather condition so I don't think it's
related a bad signal reception.

I'm going to unapply the patch and test again after repairing the database.

Best regards,
  Eduard
