Re: [linux-dvb] Help! I cant view video. BUT I can scan!!

[Per Blomqvist <p.blomqvist@lsn.se>]

The channel isn't encrypted.
(I have tested with many public chanels, that I know isnt encrypted. 
Cant get any video out)

Im Debian-tesing user, and this is a freshly installed system. On a amd64..
(as I mentioned, in previous email)

Turns out "/dev/dvb/adapter0/dvr0" isnt the only device that doesnt work.
(framebuffer didnt work ether, "/dev/fd0" are missing totaly, regardless 
of bootloader vga=791 options or so).

I removed (by now mistake) older kernels when I distupgraded, cant 
nerrow down the error search, by testing other linux-kernels.
(since I only have one, the 2.6.22-3-amd64)

And snapshot.debian.net didnt record any older.. Only option left, to 
start compilling by myslef.
(but to rough)

Probably testing another distro (Ubunto) next week.

Whatever frontend I test, it will not work.
The device, never stream anything.

I can tune, but not view the video.
(thats it)
