Hi,
I've been
implementing MythTV using Xbox as frontend, and have run into a problem that I
believe (after searching google and the various lists) needs to be fixed with a
new configuration option. I am planning to add a new 'MonitorAspect' option to
the appearance setup section that can be switched between '4:3' and
'16:9'.
The problem
basically is that on systems where the pixel aspect ratio is not the same as the
display aspect ratio (such as an Xbox displaying 640x480 but stretched to 16:9
when displayed on a widescreen TV) there is no way to tell MythTV that the
aspect ratio is anything other than the pixel ratio - that is, there is no way
to tell MythTV that pixels are not displayed as squares.
The existing
AspectRatio options (in the popup menu during playback/live tv and the override
version in the setup screen) would continue to function - these effectively tell
MythTV the aspect ratio of the content it is playing, if it cannot determine
this itself.
This option would be
similar in function to the '-monitoraspect' option that can be passed to
mplayer. I know that on some systems it may be possible to configure X to return
the correct monitor aspect to Myth, however, the X display width and height
options are not currently always used by X, and not all video cards/tv output
chips will support these modes.
I'd be very grateful
for feedback on this idea before I submit a patch, or please shoot me down if I
have completely misunderstood something...
Cheers,
Chris
