If you mean to record OTA broadcasts, there are several cards that
will do that. Some will also handle unscrambled cable; what's
unscrambled depends on your cable company, but in many cases it's just
their carriage of the local broadcasters. Recording from other
sources such as a cable or satellite STB is possible but not for
beginners.

Popular brands are ATI, Fusion and MyHD. MyHD is more expensive than
the others, but I recommend it because it provides hardware decoding
of the MPEG2 bitstream, which hardly taxes the CPU at all. A 1 GHz PC
is plenty fast enough. The MyHD will work under Windows 98SE, but
with limitations: no Firewire support, and a 4 GB file size limit on
FAT32 volumes.

Output is component, or you can add a DVI daughter card. It's
independent of the PC's normal video output, except that you can
overlay the picture on the PC screen if you like.

The software stores the ATSC transport stream to hard drive. Plan on
buying some big drives, and maybe a removeable drive bay to swap them
in and out. Figure about 8-9 GB/hour, more if you store the entire
transport stream (which may contain several channels, especially on
cable). You'll be surprised how fast your drives fill up.

There are simple and often free tools to strip out just the subchannel
you want, edit out commercials, repair transport stream defects, etc.

After writing all that, I just noticed the .au in your address. Is
that Australia? If so, all bets are off. I have no idea what's
available in Australia.

We get free to air HD. I dont have payTv and don't want it.

Just wanted to know. Would not need to unscrable anything just record
it. Maybe decode it on the fly or mp4 format or somthing.

Thanks.

But what format does Australia use? The cards I mentioned handle only
ATSC, the U.S. format. If Australia uses DVB-T or some other format
those cards won't work, although I think there are others that will.

A quick Google search indicates that Australia does indeed use DVB-T,
and there are several manufacturers of tuner cards for PCs, including
DVICO Fusion and AverMedia. Check out this page:

My Spidey Sense detects a response soon from Bob Miller.
