Thanks Michael. I won't be able to try it for a day or two, but I'll be sure to return with results.

Brian-

Looks like your X11 setup is correct. Are you using mplayer or xine for DVD playback? I would start debugging by looking at log output from whichever application you are using for the DVD playback. Feel free to post it to the list. Either enable log output if the application supports it or redirect it using something like this in your Myth setup:

mplayer -fs -zoom -quiet -vo xv -dvd-device /mnt/dvdrw dvd:// >> log 2>&1

It might even be easier playing the DVD directly from .xinitrc with various options so you are able to 'startx' and view the output until you replicate the problem and/or find the solution. For example, something like this in your .xinitrc:

exec mplayer -fs -zoom -quiet -vo xv -dvd-device /mnt/dvdrw dvd://

Hope this helps.

Hello all,

My question involves playing DVDs on MythTV. I currently have MythTV (the front end AND back end) installed on an Intel Mac Mini running Ubuntu 7.10. Everything works fine so long as I use a computer monitor running at 800x600 or better.

I've purchased a DVI->SVideo dongle for my mac. If I set the resolution to 640x480 (**), everything displays on my TV fine except for DVD playback (*). If I attempt to play a DVD while my Mac is connected to my TV, I hear sound, but I see a blue screen. If I play the same DVD while the unit is connected to a computer monitor (running at the same resolution, mind you) the DVD shows up. However, the DVD image is stretched....it should have black bars above and below it. Instead, the image is zoomed, pushing parts of the image off of the left and right hand sides of my monitor.

(1) How do I get rid of the blue screen when using my TV as a display?
(2) How do I correctly resize the DVD playback?

Thanks to all those who take the time to read/respond!

(*)   I have no over video content to play (I don't have a TV card). By "everything", I mean "the MythTV UI".
(**) Here is my xorg.conf file. I have a LOT of comments in it, so for everyone's sake, I've removed all of them.
