I can "dvbscan" and "tzap", and gets indication of a good signal. BUT,
I cant view the video!
(from the dvb device)
Also "dvbdate" command works (that returns time and date from the air, I
presume). But not a command as "dvbsnoop" (that need
A sample: ( Its step by step of your guide:
In one console I run: /.tzap# tzap -r -c channels.conf "TV4 Öresund" (
and are getting lines as:
status 1f | signal c3c3 | snr ffff | ber 0000004a | unc 00000000 |
status 1f | signal c3c3 | snr ffff | ber 0000004e | unc 00000000 |
AND in another console:
mplayer -v /dev/dvb/adapter0/dvr0
(thats basically halts without any further information)
ALSO if I type: "cat /dev/dvb/adapter0/dvr0 > afile.txt"
(But then again, "afile.txt" remains empty)
Conclusion, /dev/dvb/adapter0/dvr0 never returns anything. This
"/dev/dvb/adapter0/dvr" isnt proper. Must be a Linux-kernel/module
Here are some further info of whats on my system:
* Media Card: "Asus P7131 Hybrid"
(This very same Media-card worked on an older machine, an old Pentium,
that I now abandoned. Maybe I used the line "card=112 i2c_scan=1
tunar=54 gpio_tracking=1" when loading "saa7134" kernel-module, for
this. By a gento wiki-tips (http://gentoo-wiki.com/HARDWARE_saa7134). I
tested this line on this AMD64 machine also, but didnt make any
* Linux-kernel, "2.6.22-3-amd64" (The only kernel I see in my
Debian-testing apt list, cant use any other kernel, strange also..)
* The system, Its some dual AMD64, mother-board Asus "M2A-VM HDMI" (a
card with most stuff built-in, as sound graphics.. etc) A common card
(for building computers aimed toward media, as this is).
* Mplayer (for what its matter, gnu "cat" dint work ether, so it doesnt
matter). I have compiled Mplayer myself, with everything possible
included. Also, I have tested Debians deb-package called the same name,
but without success (or difference).
Maybe I could include the returns of the old and new "lsmod", but the
only difference there regarding this is, that I now dont use Alsa (sound
system). Now I use the default outof-the-box-configurations (a fresh
installation, this my system is, now). So I dont include what "lsmod"
returns, in this email (because then I can continue with "lspci" "dmsg",
and all possible and impossible sniff logs.. I dont know what may be
relevant info, to solve this.
Any comments and Ideers are welcome! !
I just signed up for this mailing-list ( I hope this is the right
forum.. thanx again. Also I hope the solution is simple.
Mvh, Per Blomqvist
