I'm doing this with a Canadian satellite provider, actually. This
provider provides both analogue and digital channels, although many of
their digital channels cost extra money to subscribe to, so I have very
little. I'll have to double check my settings, but I wouldn't be
surprised if I was just using Broadcast.

What kind of cable to you have connected to your Hauppauge card from
your receiver?

And you are using this with Comcast right? What digital settings
should I be using? QAM 256? Broadcast?

I've been able to record analogue cable just fine by doing:

cat /dev/video0 > output.mpg

And this was with a Hauppauge PVR-500

But now I'm trying to do digital with a Hauppauge WinTV-HVR-2250, which
doesn't have analogue support under Linux yet, but does have digital
ClearQAM and ATSC support. I am able to tune in digital channels, but
the quality is really poor and there are lots of artifacts. I'm
wondering if I'm using the wrong settings or something.

Does anyone have a card like this?

Perhaps I'm not understanding your question, but I've used an old
Hauppauge WinTV card in my desktop for years:

mark@mepis8:~$ lspci
[...]
00:09.0 Multimedia video controller: Brooktree Corporation Bt878 Video
Capture (rev 02)
00:09.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture
(rev 02)
[...]

Works great with tvtime.

I have, with Myth.. I've used both an analog and digital tuner/receiver
with my Hauppauge capture card.

[BLUG] Digital TV tuners and Linux

Anyone here have experience with digital TV tuners and Linux? Maybe
someone has setup their digital tuner with Myth or something? I'm
wondering what settings are working for you and if there are other
programs besides Myth that have been used.
