[Mplayer-users] TV Out

[Anders Rune Jensen]

Wow!!

I have been looking for a solution like this ever since I started
subscribing to this list. I have a Toshiba Tecra 8200 with a Trident
Cyberblade XP. As of Xfree 4.1.0-6 (debian package) xv doesn't work yet.
And I havn't even started on getting the tv-out working. I have a remote
control :) The machine is quite powerfull p3 750, 256 mb ram, so maybe I
can try the svga that you're using. Could you provide me / others with
more detail. This looks quite promising.
