    This may be a daft question but will a dvd recorder with HDMI, such as the soon to be released Toshiba rdxs64, be able to record hi-def from Sky tv when it comes out?

    AIUI the DVD recorders currently being launched with HDMI are using HDMI for OUTPUT only. They take the standard def DVD video and scale and upconvert this to HD for output via HDMI.

    AFAIK the only way of recording Sky HD broadcasts to DVD will initially be to take the standard def analogue RGB SCART output from the Sky box, and record this in standard def on the DVD recorder, as you would a normal Sky box. The quality should be a bit better than regular SD Sky, as there should be fewer compression artefacts on the source, and the source pictures should be higher quality (less SD noise, fewer aperture correction artefacts etc.)

    There are a couple of issues that stand in the way of DVD recorders that cope with HD recording IN HD...

    HDMI carries uncompressed HD video - any HD DVD recorder will need to be able to re-compress this for recording onto HD DVD or Blu Ray. This will require an HD MPEG2 or HD MPEG4 encoder - these are only just reaching the consumer level in cost terms (the HDV Sony and JVC cameras are the first consumer devices to contain HD MPEG2 encoders)

    There is also the copyright issue - whether recording an HDMI signal will be allowed.

    (Don't be confused by D-VHS and BluRay HD recorders on sale in the US and/or Japan. Neither of these contain HD MPEG2 or MPEG4 ENCODERs - instead they take a feed of the compressed HD MPEG2 video as received off-air via a Firewire connection. Sky's HD receiver is not going to offer this...)
