[linux-dvb] Re: FIX: 'ARM Crash' while zapping

["Andre Neumann" <chef@andre-neumann.de>]

Wow Oliver,

this is THE fix of the year 2004. I havent tested it, because my VDR is
at my business at the moment, but if it really fixes the problem you are
the man of the year :)

Great work and a BIG thank you
