I recently received my Media TV Pro stick and got it work to watch analog TV via cable (Gremany) and FM radio..
First I tried to watch with 'tvtime' but that results in frequently lost frames with short stuttering during playback. 'xawtv' however works fine. I am using the latest driver dd Aug. 20th on Debian-Wheezy-amd64, CPU and graphics card is Ivy-Bridge i5-3570K with Intel HD4000 graphics.
I tried to record using the OSD-menu of 'xawtv', but this results in an error messages and says:
xawtv -c /dev/video0
This is xawtv-3.102, running on Linux/x86_64 (3.2.0-3-amd64)
xinerama 0: 1920x1080+0+0
Alsa devices: cap: (null) (/dev/video0), out: default

oss: open /dev/dsp: Datei oder Verzeichnis nicht gefunden
The Sundtek driver however creates /dev/dsp0. I tried to create a symlik 'ln -s dsp0 dsp', but that doesn't work either.
Then I tried to record usig 'mencoder' from the command line:
mencoder -tv norm=PAL-BG:device=/dev/video0:fps=25:buffersize=64:adevice=/dev/dsp0:amode=1:audiorate=48000:input=1 -af format=s16le -ovc lavc -lavcopts vcodec=mjpeg -oac pcm -o test.avi tv://

Exiting...
I am quite sure the proper codecs are installed, also I can watch smoothly on the screen.
The driver itself reports:

Any hints how I can manage to record analog-tv?
With best regards,
