Is 720P 50 Hz output possible?

[PhilEndecott]

Dear All, Is it possible to get 720P output at 50 Hz (or 25 Hz) ? 30 and 60 Hz work for me, but 25 and 50 aren't even options in the tve.c source. Yet 1080 is available at those frequencies. Is this just something that's missing from the driver, or is it a fundamental hardware limitation? Regards, Phil.

In the same vein - what about RGB with SD TV timing, as would be needed for a SCART connector? This doesn't seem to be supported in tve.c, though looking at that code it seems possible that the hardware supports it.
