Hi there I've got my new EPIA VIA-based frontend all operational, and am now able to deal with the more "niggly" issues than outright flaws that faced me earlier :-) One of them is that mythtv seems to think our TV screen is bigger than it really is - so there is a wee bit missing from the left, right and bottom. e.g I can only see part of the first letter on the initial screen on the TV - and can't see the "Next" button at all on the bottom right. All looks fine when viewing the system via VNC from another box - so it must be a TV monitor issue. Is this something to solve within mythtv, or is this an xorg.conf issue? If so, can someone give me some pointers? Our current TV is an old Sony Trinitron if that makes a difference.

Well I'd like to know a good solution to the Via Epia TV out as well but in the meantime check out this thread on the knoppmyth forums: http://mysettopbox.tv/phpBB2/viewtopic.php?t=10049"]http://mysettopbox.tv/phpBB2/viewtopic.php?t=10049
In my post I explain what I did to get the display to fit the screen. The only problem is when you watch DVDs or Videos that you will still get the overscan.

Television is naturally overscanned. Normally input video takes this
into account, and ensures everything you *must* see is actually some
ways from the edges of the video.

You need to take that into account with either a modeline that puts the
"visible" video inside the actually physically visible part of your TV
(and it will vary from TV to TV), or make a modeline that matches a
proper overscan output, and then make MythTV use a smaller GUI size.

I did the latter. I think it results in a better output, because the
capture from any source will include all that overscan picture as well..
so if you *do* make the visible portion in X fit your TV, you have to
trim the video you've captured as well.. etc..
