OK, I think the trouble is my graphics card (the nvidia 6150), which is built onto my motherboard. The only thing stopping me from switching to a card like the nvidia 7300GS, is that the only reason I bought my motherboard (an MSI mini-atx thing with PCI-E, and DVI out) was because it has onboard DVI. And I can't find a 5300FX anywhere (I need a PCI Express GFX card).

http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users</a><br>><br><br><br>I don't mean to discourage you, but having actually worked on a set-top<br>box, I'll say this up front - with MythTV (or any other Windows/Linux
<br>program), it will be very difficult to get set-top box quality. Set-top<br>boxes have video output chips that are optimized for MPEG-2 playback, and<br>they also take into account all the little things that are necessary, such
<br>as perfect vertical sync timing (for page flipping without tearing). A<br>general purpose Linux system just can't get *that* good, but it can get<br>pretty close. A lot of good discussion can be found here:<br><a href="http://www.gossamer-threads.com/lists/engine?do=post_view_flat;post=116194;page=1;sb=post_latest_reply;so=ASC;mh=25;list=mythtv">

<br>or ESPN (ESPN has fast tickers, so any artifacting in the display is<br>really noticable).<br><br>Here's what I've got:<br>- GeForce 5200FX connected to an HDTV monitor running at 720p (1280x720)<br>via VGA (60Hz)<br>
