Re: xawtv - no picture

[Ian Davidson <id012c3076@blueyonder.co.uk>]

The card has 4 sockets on the back
- FM Antenna
- UHF/VHF antenna
- S-Video
- Remote sensor.

This time, I tried plugging the camera into the S-Video (rather than the 
FM antenna - oops!) but it didn't help - still a black screen.

I ran xawtv with the -v 1 option and got this

[Ian@localhost ~]$ xawtv -remote -nodga -c /dev/video on card=114 -v 1
This is xawtv-3.95, running on Linux/i686 (2.6.25.11-97.fc9.i686)

I have been writing programs for almost 44 years - but I blunder round 
linux like a newbie.  I appreciate all the help you can give me.  Please 
let me know what else I can do to get this working.
