Hi Greg, I'm new at this as well (I'm working on getting a 350 up and running) but will offer a few things I have found out relating to your questions:

Try it with a -h to get a list of the flags you want. -N Will list the available outputs. -L Will give you the actual output being used. There are flags for inputs etc as well. If you are using Fedora or similar I believe you can do the following type of thing in /etc/modprobe.conf: options ivtv set-input=0 Likewise for outputs etc. >b) How do I do the test_image feature that the docs describe.

I get the test pattern without difficulty using his instructions. http://wilsonet.com/mythtv/fcmyth.php?SID&expandables=closed&ivtv=open&pvr35 0out=open >c) Where do I find ivtv-fb?

Either at boot in modprobe.conf or later with manual modprobes. > >-- >greg > ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ ivtv-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/ivtv-devel
