recording playback and live tv display 'wrong'

[rusty@…]

Had a hard drive fail, so I re-built my mythbuntu box from the 8.10 default cd. All back end features are working as I would expect, however playback of either a recording or live tv gives me a display that uses the center third of the screen only.

The appearance is as if the recording was 480x480, and the playback was letterboxed to 720x480.

Adjusting the recording profile for the PVR-x50 cards does not affect playback of live tv or recordings on this front end.

The recordings appear to be being captured correctly. When I play them back on other front ends, the display is correct.

The front end I am using does this with all tuner sources, including analog cable (pvr-250, hvr-1600 analog side) digital OTA (hvr-1600 digital side and hdhomerunner) and Cable (hdhomerunner)

The UI, music player, photo gallery all use the full screen without any problems.

I have tried altering the capture resolution on the pvr-250 recording profile from 720x480 to 480x480, without any noticable change. Setting horizontal scaling to 25% results in the left and right edges of the image being clipped, however it still uses the same 'window'

The 'window' is applied to 'zoom' levels 'none' 'half' and 'full'. Setting the zoom level to 'stretch' uses the full screen, however the top, bottom and right and left edges of the image are all clipped.

My suspicion is that there is a control for the internal player that is not being handled properly.

The intel drivers for xorg were made available last night, and after installing them, no change detected.

Playback is through a dvi-hdmi adapter to a projector that displays properly from my PS3 (at 1920x1080) but which I have to set this system to 1600x1280 to work with. 1920x540i comes up with a different layout for the UI every time I try to use it.

Attaching lspci -vv, Xorg.1.log and mythbuntu.log. Will be happy to attach other logs and captures of frontend being launched from a command line if that would be helpful.

correction, not Xorg.1.log, but Xorg.0.log, and not mythbuntu.log, but mythfrontend.log are the attached files at this time.

Since you are saying this "used to work", this would seem to be a configuration issue.

If Xinerama is used on the X server, you need to tell the frontend (in Settings / Appearance) the monitor aspect ratio. Does specifying this fix the behavior?

I don't believe Xinerama is being ussed. It is not listed in /etc/X11/xorg.conf and I don't recall requesting or seeing any reference to it during the install.

That said, swting separate video modes for playback and gui, even if the modes are both the same, but now setting the aspect ratio does resolve the issue.

I take that to mean that Xinerama is enabled by default on my system. I gather one other option would be to add a line 'option "xinerama" = "no"' or something like that in xorg.conf.

So yes this does turn into a 'fixed' issue, though I'm thinking that it needs to be better documented, and may need to be an option in something other than using different screen resolution modes for Gui and playback.

I'm also seeing a possible configuration issue that will bring some confusion to this issue. On page 2 of 9 of the Appearance series of dialogs there is a checkbox tu 'Use GUI size for TV playback' then on page 3 of 9 the entire page is dedicated to setting different video modes for GUI and TV playback, which only opens if you select a check boxx on that page that reads 'Separate video modes for GUI and TV playback'

I suspect that they refer to something different, but it looks like they are two checkboxes for the same thing.

Have you looked at the setting I specified?

Xinerama is default on most X11 installs which can be multihead.

Yes, see above, I think this resolves the issue I was having. I was not aware of the Xinerama being enabled by default, and I had not found any reference to the effect I was seeing. I'll have to watch out for this when I upgrade to 9.4 or later I suppose.

Thank you.

Thanks for the quick response!
