    Are there any affordable single boxes which deinterlace and scale?

    If not, can you use a separate de-interlacer and scaler in the same setup (e.g. Tv-4000 and IScanPro)? If so, does it matter how they are connected?

    About £600 - £700.

    I've just ordered a TV-4000 (otherwise known as ProV) because it is BOTH a deinterlacer and scaler....and it's relatively cheap.....and I've read good things about it.

    If a de-interlacer lacks 2:2 pulldown, what is going to be like with PAL sources?

    Will a unit purchased in the US work in the UK (voltages and connections etc)?

    Can you wire a separate de-interlacer and scaler in series?

    Are there any cheap scalers that can accept a progressive signal without just passsing it through untouched.

    2:2 pulldown is only a requirement for playing back software which originated on film and is now in 50hz pal. This could be braodcast films on tv. or video or dvd.

    So, If I buy a unit with no 2:2 pulldown, what would it do for PAL DVDs? Would it work at all?

    Yes it would work and create a progressive output for PAL 50Hz but it would not produce optimal quality progressive frames from film sources recorded to video with a 2:2 field sequence such as 25Hz and 30Hz film sources.

    Having both 3:2 and 2:2 pulldown detection and compensation will potentially allow the de-interlacer to create perfectly de-interlaced video frames for all film sources on both PAL and NTSC video formats.

    Ludae: I think the thing that confuses everyone is that they think that DVD require 2:2 and 2:3 as that is what this feature is most discussed with.

    Everyone:
    Having 2:2 and 2:3 pulldown is of no benefit if the DVD in question was recored on a video camera (eg concert footage) or if you are watching the news at ten....these are most likely recored on video cameras and require a different de-interlacing algorithm to film based material or static images....
