Hi guys. New to xbmc.

Running latest version on debian 6. I have a GT430 and a Mitsubishi 65" DLP.

I'm having a problem when playing 720p content. 1080p content is fine. But when playing 720p, xbmc switches video modes on me (although me tv still reports 1080p, I can see it switching modes -- different refresh rate I guess), and then I have an overscan problem.

I calibrated via the xbmc system options but it seems to only calibrate the first mode (1920x1080x60hz). I'm unsure how to calibrate the other modes.

Here is my xorg:
Code:

    Identifier     "Monitor0"

    ModelName      "Unknown"
    HorizSync       15.0 - 68.0

Comment out "1280x720@60" mode from xorg.conf and let Nvidia do scaling.

I tried this, and it made no difference. The regular menus are all fine (no overscan). 1080p movies are fine. 720p content is still hitting my TV via 1080p (tv not switching to 720p) and there is bad overscan that needs to be fixed.

hi,

Start a 720p movie, when it is playing push enter to open the osd and go to video settings. scroll to the bottom and you will see video calibration. Enter and adjust the overscan then exit. Next time you start a 720p movie the overscan should be corrected.

Well, I figured out that XBMC wants to use 1920 x 1080 @ 24 for most all my content. I had my default set to 1920 x 1080 @ 60, so I changed that.

I also went into guisettings.xml and copied the overscan settings for each 1920x1080 and now the overscan problem is gone.
