I installed xawtv in Ubuntu for my Athlon64 system. Video and audio both are working fine now, but the problem is I'am not able to record anything. In terminal I started xawtv and it usually displays...
gopi@Gopi:~$ xawtv
This is xawtv-3.94, running on Linux/x86_64 (2.6.12-10-amd64-generic)
Warning: locale not supported by Xlib, locale set to C
Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to type FontStruct

Eventhough that Warning gets displayed, both video and audio plays fine.

And when I try to record something by right-clicking and selecting "Record Movie" and give some filename in both movie/images and *.wav and clicking "start/stop recording" it displays....
Oops: can't count up file names any more
Oops: can't count up file names any more
<this same thing continues for each millisecond>
And after some 5 or 10 secs the following is atlast displayed and xawtv gets closed !
oss: read: Input/output error

So please help me if this could be solved or can I try some other TV Application ?
