[mythtv-users] Problem with PVR-250 - zero byte mpg files

Sun Oct 19 23:24:19 EDT 2003

Hi,

I did my installation based on the same guide, and I got this problem, 
too, when I guessed the tuner type wrongly; I live in Germany, and the 
correct tuner type for me is 14, but when I tried with 2 or 5, I got the 
same error as you.

In the IVTV list they told me, that you can figure out what tuner type 
you have by loading the tveeprom module and reading its output on dmesg.

Maybe this helps.

Best,
   Joachim
