I have found that 1280x720 @ 50Hz is a mode that works well with my TV. The TV supports 49 - 61 Hz vertical refresh rate as reported by EDID. I wonder if I in XBMC setup select "Sync Video To Display" and using "resample audio" as syncing method, can I then view 23.976 fps video upspeeded to 25 Hz (the video and sudio played faster) just like they do it when viewing film on PAL TV transmissions? I am using XBMC beta 9.11 on ubuntu 9.04. I think in the windows there is an application called reclock that does a similar thing but I want it on XBMC in Linux.
This would be my preferred way of watching NTSC movies on my PAL TV.
Another question:
There is a valid mode of 720x576 that I can use in XBMC and it works when calibrated inside XBMC but on ubuntu desktop (TV is set to 16:9 display) the desktop is stretched horisontally and for instance when watching web video in firefox it gets horisontally stretched (can be fixed by setting TV to 4:3 but then the whole screen is not used).
Is it possible to set a 1024x576 modeline and use it despite of the fact that it is not reported as a valid mode by EDID? My TV is a CRT model with HDMI input and the real resolution is actually not more than 1024x576 but it can handle HDTV signals over HDMI (but probably downscaled by the TV). This is my TV:

Supported Display Resolution
Video formats Resolution Refresh rate
1080i 50, 60Hz
480p 60Hz
720p 50, 60Hz
576p 50Hz
You may ask why I not just use 1280x720 resolution on the desktop? Well the problem is that my PCI (not PCIe) videocard nvidia 8400GS seems to be too slow to upscale flash video to fullscreen because I get framedrops at 1280x720. However by using a lower resolution less frames are dropped. But in XBMC I can play all resolutions with no frame drops because of VDPAU acceleration. I have not tried playing flash video through plugins and scripts in XBMC, maybe that is the solution of my problems?
