Steve Reid:
|I just purchased a Hauppauge WinTV (Bt878) and have Fxtv working "alright".
|I have a few questions/annoyances though...
|
|When I press the "full screen" button on the remote the image goes
|full-screen like it should. But when I press the button a second time
|the screen goes black.
Sounds like a bug in the X server for your card.
To remove fxtv from the loop, try the attached program.
1. run "xsetvmode -q" to display your current resolution.
2. run "xsetvmode 640 480" to switch to 640x480
3. run "xsetvmode # #" to switch back to your original resolution (plug
in the numbers you saw from xsetvmode -q originally)
Did you see a black screen after step #3?
If so, upgrade to the latest released version of XFree86. If you
already have, report this to the XFree86 team (see www.xfree86.org
for the web bug report form.
|Is there any way to bind a remote button to flip back and forth between
|two channels like most regular TV remotes have? This seems like such a
|basic thing but I can't find any way to do it.
There's currently no "last channel viewed" feature.
|This device should be able to play cable radio... Can it be done with
|Fxtv or is there some other program I should be using?
See xmradio in the ports collection. Also:
http://www.egd.igd.fhg.de/~runge/xmradio.html
|What do you folks do to stop xscreensaver from kicking in while you're
|watching TV? I guess a script to kill the xscreensaver server, run fxtv,
|then restart the xscreensaver server would work but I'm wondering if
|there's a better way.
There may be a way for an X app to disable the screen saver, but I'm
not familiar with it. Anyone?
Randall
