Aspect ratio problem (aka: I miss my 4:3 side bars...)
I just did a fresh install of MythDora 4.0 and Iâ€™m having an aspect ratio problem.
The problem is that 4:3 standard definition recordings no longer have black sidebars (pillarboxes). 4:3 playback is being stretched horizontally. Changing the aspect ratio to 4:3 has no effect (but other aspect ratios seem to work).
I have a LCD TV whose native resolution is 1280x768 (15:9). It is connected to the MythDora box via a DVI cable. The TVâ€™s on-screen status indicates that it is receiving a 1280x768 @ 60 Hz signal over the DVI cable. In my /etc/X11/xorg.conf, Iâ€™ve indicated the proper modeline and displaysize for the TV. Iâ€™m reasonable confident that the TV (which can be considered an LCD monitor at this point) is configured correctly. The menus on MythTV look great. DVD playback looks great (aspect ratio looks correct). But playback of 4:3 recordings is stretched.
Any ideas on what happened to the sidebars?
One idea that occurred to me is that MythTV thinks my TV has a 4:3 aspect ratio. When I first installed MythDora I was using a 4:3 monitor in the basement. Did MythTV store a setting that says â€œIâ€™m running on a 4:3 monitorâ€, and now Iâ€™ve defined (through xorg.cong) that â€œ4:3 monitorâ€ as being 1280x768 pixels? Is there a setting in the settings table that indicates aspect ratios?
