[linux-dvb] Avermedia 771 on Gentoo

[Ben Rometsch <ben@solidstategroup.com>]

Hi There,

I'm new to the list, but, having read through the list and searched the gentoo 
forums, am unable to get my Avermedia 771 card working on my gentoo box. 

I have a gentoo-dev-sources 2.6.5r1 kernel running. Here's what I have done so 
far: 

Grabbed a CVS snapshot of the linuxtv-dvb dated 2004-06-21 (the latest build 
was giving me compile errors as described here: 
http://forums.gentoo.org/viewtopic.php?t=146327&start=25)

applied the makelinks script to patch the kernel 

selected Zarlink MT352 based driver, as well as the Nebula/Pinnacle PCI card 
driver and some other things, as described on the gentoo forum post above. 

Compiled the kernel, rebooted, ran: 

modprobe bttv i2c_hw=1 card=0x68
modprobe bt878
modprobe dvb-bt8xx
modprobe mt352 

Which shows up in dmesg as:

Linux video capture interface: v1.00
bttv: driver version 0.9.12 loaded

But trying to scan for channels gives me:

Done. 

I'm in North London, so I am 99% sure the transmitter is right. I have had the 
card working with the same aerial under windows. Anyone with any ideas?

Thanks,
Ben
