Hi All.

I've got knoppmyth working reasonably well on a SN41G2 with a PVR-350 with the exception of the X display size. It's too big. My config is listed below. Appreciate any help. Ta.

Discovered that the issue was with the TV. I've played around with XF86Config and myth's display size and am happy with the result.

Cheers

Ric.

What changes did you make?

UD.

You can change the mythtv display size in mythtv under: Setup=>Appearance changing the GUI height, width and X and Y offsets in the Screen Settings screen.

I did make changes to the PAL settings in XF86config but the xdisplay is still overscanning (if that's the right word) but I don't use anything but the mythtv display so who cares.

Cheers

Rick.

Do you watch DVD's with your mythbox? I'm curious because I have not yet found a combination of myth settings that allows the myth GUI to be tweaked correctly without distorting DVD playback. That is, DVD playback looks stretched or squashed unless I keep myth GUI scaled to 4:3. And if I keep myth GUI scaled to 4:3, it will invariably be heavily over or underscanned.

I have experimented with tweaking myth GUI to a non-standard scale and then scaling DVD playback BACK to normal with mplayer command line calls, but find this will not work consistently for panscan AND letterbox settings. If I tweak letterbox to look right, for instance, the panscan will look really bad, or vice versa.

I see new settings in 0.15 that allow tv and GUI to be scaled differently, but do not have much hope for these as DVD playback seems to follow myth GUI resolution settings, whereas TV playback seems to have a mind of its own (nothing I do to myth GUI effects tv playback at all, nor do the tv OSD overscan/underscan settings either though!).

Any body have any advice on how to tweak myth settings to get all aspects of myth to appear correctly on a tv screen?

thanks --sa

I don't watch DVDs with mythtv as my DVD drive throws errors below. I suspect it has something to do with DMA with the DVD drive but haven't been able to fix it yet.
