Win-TV HVR 950

Good daytime to you.
I got this toy! XD it's a usb tv tuner + s-video/composite input

Google came up with some articles about setting this up in linux (the original soft for windows in widows works horrible, giving me a fullscreen rate of 1 fps)
accordint to them v4l-dvb driver should do the job.

Before installing the driver, i just plugged the toy and TVtime detected it, and composite/s-video in works perfect, i get a good image, but tv tuner never wants to catch a channel - i have broadcast antenna and cable available. In windows cable catches 60 channels, just like its suppose to, and antenna - only 2, but that's not a surprise, i live quite far aways from the tv towers.

after yaourt v4l-dvb  - there was no change

In TVTime settings I tried to change frequency tables, cable formats... nothing. MythTV does the same - hardware is recognized at /dev/v4l/video0, but can never find a channel.

so, is there a way, maybe to scan a whole frequency range available, or maybe there is a freq. table I can fing that suits my location (USA, Louisiana; suddenlink cable), or do I need a different driver?

Re: Win-TV HVR 950

Hey! Great news! Turns out all I had to do was tyo copy the firmware, and vuala - it works. One trouble though - tvtime gives me picture and so sound. mplayer, on the other hand, when i call it with

mplayer -vf crop=640:468 tv://51 -tv driver=v4l2:alsa:immediatemode=0:adevice=hw.1,0:norm=ntsc:chanlist=us-cable

plays perfectly!
what can be wrong with it?

Re: Win-TV HVR 950

You can try the classical solution for no sound in tvtime:

sox -r 48000 -v 1 -c 2 -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp & 
tvtime
killall sox

sox is in Arch Linux repositories.
Bye

Re: Win-TV HVR 950

this was sound does apper to be from the tv, but its clipped baddly - i can head just an instant and then its silent for a minute or two. Here is the responde of the code:

Running tvtime 1.0.2.
Reading configuration from /etc/tvtime/tvtime.xml
Reading configuration from /home/hexorg/.tvtime/tvtime.xml

Input File     : '/dev/dsp1' (ossdsp)
Channels       : 2
Sample Rate    : 48000
Precision      : 16-bit
Sample Encoding: 16-bit Signed Integer PCM
Level adjust   : 1 (linear gain)

In:0.00% 00:00:00.54 [00:00:00.00] Out:24.6k [  ====|===-  ]        Clip:0    sox sox: /dev/dsp1: lsx_readbuf: Input/output error
In:0.00% 00:00:00.54 [00:00:00.00] Out:26.1k [      |      ]        Clip:0    
Done.

Re: Win-TV HVR 950

oh yea, In /dev I have /dsp, /dsp1, /dsp2, and /dsp3, maybe that has something to do with it too?
