SDTV: 16:9 video is being compressed to 4:3
Hi,

I'm running Xbian on an old 16:9 PAL CRT (SDTV, I use the TV's "zoom to 16:9" mode to stretch the 720×576 to 1024×576). I just updated to the latest build running Kodi 16 (coming from 15.2) and have a strange problem: Kodi plays all 16:9 video compressed to 4:3; 4:3 video (which is set to display as normal) is compressed even further. The Xbian boot logo and the Kodi GUI display as expected (16:9, covering the whole screen). Everything was fine and worked as expected on Kodi 15.2.

In my /boot/config.txt, I set the correct PAL/16:9 resolution (didn't change anything recently):

Code:
sdtv_mode=2            # normal PAL
sdtv_aspect=3          # 16:9
disable_overscan=0     # enable overscan
hdmi_ignore_cec_init=1 # doesn't sent initial active source message
hdmi_ignore_cec=1      # pretends CEC is not supported at all by TV

Is there any explanation for this, or any setting in Kodi 16 I could tweak to get things to work as expected?

Never connected RPi to old 16:9 PAL CRT, will see if I can found a cable so I could try it.

Sounds really strange.

All Kodi settings already tried?

Anything under Settings/System and Settings/Video, yes.

I'd try commenting out your config.txt settings, it MIGHT be confusing Jarvis which seems to work better with most configs.

If NOT, post the output of dmesg, and kodi.log (via pastebin - as defined in the read before....) it might show up something.

I too, no longer have a CRT - upgrade to a modern TV :-D

Please read before you post

No, they are necessary for SDTV

Kodi Jarvis has issues with interlaced resolutions

Just tried again after some time with the current XBian version with the same effect. I got some logs, this time around:

kodi.log/xll: http://paste.debian.net/686880/
dmesg: http://paste.debian.net/686881/

Maybe someone can deduce the problem from those?

Thanks, the version linked there solved the resolution problem. So whatever was done differently with this version, please include it in the stable releases if possible.

I still reverted back after a few hours though, as video playback was jerky at times (video would play fine for 30-60 seconds, then there would be a slight freeze of probably anywhere from 10-30 frames, then it would play fine again for another 30-60 seconds, slightly freeze again). Audio was fine all the time though.

I've had this behavior before, I think with Helix or at least an older build of Isengard last year and it eventually went away with an update. Not sure if this is a know problem or not.

It's not known and never happened during my test phase.
