    Have I got this right??

    When watching a DVD on Projector

    The HTPC outputs the DVD be it PAL or NTSC in progressive scan.

    The HTPC can scale the image to match the projector panel resolution bypassing the projectors internal and probably inferior scaler. (You use Powerstrip to create the custom resolutions to match said panel resolution.)

    Is it the PC that does this itself or the DVD software?
    If it does the de-interlacing and scaling itself then wouldn't the output from a TV-Tuner card through the VGA port also be de-interlaced and scaled? Why then is a program such as DScaler required?

    After a bit of research...Dvd software does de-interlacing etc, DScaler just does it better??? AND deinterlaces sources input via TV/capture card??? Have I got a grip of this yet? :)

    OK next question:D Recommendations for TV/Capture cards!!

    Right here goes:

    DVD software will deinterlace DVD based on the flags present on the disc, for mainstream film titles this is perfect almost all the time. For video sourced stuff, which are sports, documentary stuff and music then a good DVD program with a Radeon will do a decent job of deinterlacing.

    For any s-video - composite input you can use the supplied TV prog which will deinterlace but will do so badly (usually they just weave the image) or use Dscaler to deinterlace and it mostly does a reasonable job but will not match a DVD prog because of the additional d/a a/d step.

    As far as cards go ther Falcon seems to be the best off the shelf card.
