[linux-dvb] Re: Triple packet problem

[Andaka Wahyu Adi <kcho@slank.com>]

Hi,

I've tried this patch on dvb-20030512.tar.bz2, dvb-20030529.tar.bz2 & linuxtv-dvb-1.0.0-pre3.tar.gz but none fix the problem.
Any idea....

Thanks.

B'Rgrds,
Andaka Wahyu Adi


BTW I'm using Dell Opti Pentium 233 MMX here's my dmesg:
