    Force TV to deinterlace HDMI signal?

    I am not satisfied with the quality of HD display on my TV, and got to thinking - is there a way to force the TV to do the de-interlacing? It deinterlaces QAM signals really well, so why not let it de-interlace the HDMI signal?

    I removed the deinterlace filters in MythTV (still using VDPAU) and the results were horrible!

    I don't know enough about HDMI, X and Linux to know if this is possible. And if so, what would I need to do?

    My hardware:
    Video chip: NVidia 8200 on ASUS motherboard. Assigned 512MB in bios.
    Processor : AMD Athlon 64 2.7 GHz. Processor speed set to 2.4GHz.
    Memory 2GB.

    I am using Mythbuntu 9.10 and have upgraded to the 195.xx nvidia driver using the JVA repo.

    Any help is appreciated, including pointers to sites that I can learn from.
    Thank you.

    The TV's "native resolution" is 720p. I assume that the I am driving it at that resolution. How do I figure that out?

    I was thinking if I could drive it at 720i, it could handle the deinterlacing. However, I don't know that it can, and was hoping someone here would have the answer.

    TV is a Samsung LN32A450
