I You don't need to do that - you can just set the BKTR_FREQUENCY environment variable and nuvrec will tune to that frequency (this works for ffmpeg too BTW) - you can also set BKTR_DEV to select the input channel.

Hmm, there will be no audio if nuvrec fails to open the tuner or the pcm device. Make sure that fxtv isn't still running and check permissions on the tuner and pcm devices.

Try tuning with BKTR_FREQUENCY - it sounds like something has adjusted the tuning for you. CS> Do you have other multimedia apps you prefer for this simple task? I've gone back to ffmpeg - because mencoder has a habit of crasjing when used in a nuvrec pipeline. I've got ffmpeg 0.4.8 making DVD format recordings straight of the air now (with a little help from mpeg2desc, mplex and dvdauthor).

Yesterday I typed this: at 0010 vcrdvd bbc1 105 Air_America This morning my /data/video partitition contained a directory called Air_America with a DVD format video in it :) Was that the kind of thing you were aiming for ? -- C:>WIN | Directable Mirrors The computer obeys and wins. |A Better Way To Focus The Sun You lose and Bill collects. | licenses available - see: | http://www.sohara.org/
