[mpeg2] Re: KFir and kernel 2.4.19 / 2.4.20

[Andreas Krings <andreas.krings@rwth-aachen.de>]

Hi,

i have had the same problem with 2.4.19 after deleting the "busy-struct" 
(like you). My Problem was the wrong microcode from Windows (for some 
reason, the script got the wrong code from my win2k installation, 
checksum was wrong), so i downloaded the binary kfir driver and 
extracted only the microcode and now it works great! The adress for 
downloading the kfir binary is in the faq!
