Sky HDTV to PC recording

Hi,

I want to use the HDMI output from my sky box to connect to my PC via
a PCIe card or external unit, so that I can record HDTV on my PC. As
far as i know my graphic card is HD DRM compatible, but does anybody
know who makes hardware in the form of thePCI express card or
similar.... or has anybody done this?

TIA

Does the HDMI output on your SkyHD box output an MPEG-2/4 stream to an
external decoder in your HDTV or an uncompressed stream. If it is
uncompressed then the bare minimum hardware requirement to be able to record
the stream in real time is a processor which is 5 times faster than anything
that exists today in a PC. I doubt even SATA-2 can handle recording an
uncompressed 1080i stream to disk in real time without saturating.

people who capture sky HD tend to use specialised satellite receivers with a
dragon cam or the like to capture the transport stream - not a regular sky
HD box.

Most new cpus today can just about comfortably decompress HDTV. Realtime
compression would be beyond current cpus. The other guy said you could use a dvb
card with a dragon cam. While that does probably have some problems compression
isn't one of them so try that instead. A bonus would be that you could also
record both HD and non-HD channels at broadcast quality.

Actually experience with Nebula DigiTV with H.264 decoder - (one of the
only software solutions which can decode the BBC HD trials on Freeview
in London) seems to suggest that only top-end PCs (~dual 2800+ or
higher) can comfortably decode HDTV!

my 3ghz p3 can decode 1080p without dropping frames if i use corecodec.
using the usually low on cpu usage vlc player gives just a stuttering mess
however.
