Live TV Preview in EPG has wrong aspect ratio

Description

When I open my Guide from Live TV, the preview of the currently tuned channel in the upper right corner has the wrong aspect ratio. I use a 4:3 setup, but the preview only shows the left ~2/3's of the image as if it was trying to show a 16:9 preview.

The previews for recorded programs display correctly.

I don't know if this has been fixed since the bug report, but this appears to work for me. I tested with G.A.N.T. and MePo?-wide on a 4:3 screen with square pixels and both 4:3 and 16:9 content was previewed correctly using both themes in the EPG.

Still happening as-of r13345. Maybe I have a bad setting lingering from when it happened on that box?

I've always had this problem too. I use Knoppmyth, started around Myth 0.15 and am currently running 0.19. I have 16:9 display, and use proper 16:9 modelines, and the preview still only shows about the left 2/3's streached out. This is true for both 4:3 and 16:9 source material. I've come to assume it is hardware related but don't know for sure. I don't see it on another front-end so it doesn't appear to be related to the back-end hardware/config. I'm using an Abit AN7 motherboard and AOpen FX5200-DV128 nvidia graphics card. I've run various versions of the nvidia drivers but the behavior always remains. Also different themes seem to have no affect.

I have the same problem, this using 720x576, non-square pixels (i.e. 16:9)

rob, does the display non-square pixels, or do you mean that the video uses non-square samples?

As one of the Robs, I am using DVB-C PAL broadcast at 16:9 and IVTV 720x576 also 16:9. I will have to verify if this happens on both tuners. My display output is at 720x576 with non-square pixels to achieve 16:9.

Overall, I guess you could say that both the display output and the video are non-square (unless I misunderstand).

Just to confirm, the effect is the same on both tuners.

Is this still a problem? It may have been fixed by Stuart M in [14865],[14866] etc. or was that just for preview images?

That was just the preview video and images in the watch recordings/delete recordings screens, not the EPG.

(In [16893]) Refs #5107. Refs #2514. Preliminary support for video playback window resizing.

Mostly committing this now so I can use the new monitor dimension variables to handle #2514 properly.

This is disabled by default. If you want to try it, run mythfrontend with "-O UseFixedWindowSize?=0".

This does not do the right thing if you enter the EPG and may not play well with display resolution switching based on video dimensions.

Tested with non-square pixels. I don't know when this was fixed, but apparently it has been.
