Don't think so, also think that not many people using this card with the linux 
driver. This card seems to be quite similar to the DVB-S and DVB-C cards from 
Technotrend, probably only the frontend is different.

 MD5 is 53970ec17a538945a6d8cb608a7b3899 so it's the same as your version.

Does this only happen if you tune to a certain channel? How is the signal 
strength of the different channels if you use tzap? Does it help to tune back 
to another channel? I remember that this happend also here, when DVB-T still 
was on test in Berlin. It looked like a crash of the frontends internal 
system controller. That's why I would like to know if this also happens with 
the windows driver, because then it could be a SP8870 firmware problem. I 
tried to change the code to get a better reset of the system controller, but 
didn't succeed. I think just reloading the dvb-ttpci module helped. Can you 
find out if that's the same on your machine? Or do you have to reload all 
modules?
