[linux-dvb] Re: [PATCH] heavy section filter crunching

[Jeremy Hall <jhall@maoz.com>]

HEY NOW! THERE's an improvement!

Now I have not had a crash and have run a channel on the "EEPG" pid for a 
long time.  I still get CRC errors, but that's recoverable next pass.

(I use hw_sections==0)

it applied with something called fuzz 2, but was ultimately happy.
