    I've been looking to sort out a HCPC in order to supply a progressive scan input to my Loewe TV, via the VGA module.

    The idea is that i'll be able to use the PC to deinterlace and scale the input (PS2/STB/DVD Player) to the video card and output using my existing graphics card (or maybe not - i'll come onto that) to output via VGA-VGA into the Loewe.

    It seems that I'll need to use Dscaler to do the deinterlacing, powerstrip to run at the right resolution. I therefore need

    a) a tv/capture card that will give me the best quality input, and also be compatible with Dscaler.

    b) a video card capable of outputting the right resolutions to supply the Loewe.

    I know from other conversations that I can run the Loewe at 720x576@50Hz and 848x480@60Hz, i don't know if there are any other resolutions I should try to run it at or even if it will be necessary? Being stupid it seems that the PAL res mentioned above is 4:3 format, and the NTSC res 16:9 - Is this right? If so do I not need to be running PAL at some other resolution to correctly display a widscreen image on the TV?

    I've heard mention of the Flyvideo 3000 card - which has S-video input - is this a good card to choose? Image quality is the main concern, sound will be handled elsewhere.

    TIA,
    Jag

    Well I tried to connect the PC to the Loewe using my existing card (Geforce 256 Pro ~ 3years old) last night with mixed results.

    At 640x480 I get a solid image at 60Hz with decent geometry.
    At 720x576 I get a solid(ish) image at 50Hz with pretty bad geometry
    At 848x480 I get a solid image at 60Hz with pretty bad geometry.

    No matter how much I play with the Loewe itself, I only have limited geometry control for the VGA module. I can't work out whether powerstrip or anything else can provide the level of control needed to end up with a decent image on screen.

    Bit disappointing really - Anyone have any suggestions - I figured I ought to try and run it at the native res for PAL dvd, as that is what i'll be playing mostly, but with the geometry as it is I don't think I can put up with it.
