I remembered xawtv-3's lack of mpeg playback, along with compiling xawtv-4 with mpeg support. I got as far as looking at xawtv git, and xawtv-3 git has quite a few recent commits. Xawtv-4 seems to lack any activity since it was conceived years ago. >The xawtv app is really old and I'm not even sure if anyone is >maintaining it any longer.

I do have good audio so I can hear either the static or the station broadcast. Most I have here on analog TV freqs are 10-20 scrambled (over the air cable in Alaska here) and one standard TV channel which is poor in quality. -- Roger http://rogerx.freeshell.org/ _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
