Re: [mythtv-users] newbie help - ATI capture card?
If you have spent two weeks on it, I'd tend to recommend, if possible
giving up and ordering a Hauppage PVR150 from newegg or your computer
store of choice. I'm trying to use cheap ATI video cards with s-video
out for front ends, which is doable afaik, but using a ATI for the
backend is probably just a path to frustration.
Of course the video out quality of video cards running Svideo is usually
sub par, with I think nvidia having the best ones and the best solution
being the hauppage one with TV out.. If you are using 20 or less tv's
you might consider seeing if you have a used computer store around you
can find some good used or just buy new monitors (They are surprisingly
affordable now). Avoiding the whole s-video issue has its merits. I
think I saw a sharp 19 monitor at one used computer store in St. Louis
at around $90.
Beyond the 20 range if you have the money, some tv's have digital
connections, and that brings with it a whole new set of issues.
Of course reading here might help...

Oh- and am I right that the card with the coax port on it is called a
capture card?

This doesn't add up so here's a quick rundown.
An ATI Rage 128 would normally be a graphics output card to
display on a monitor. It may also have s-video out, or more likely
a special ATI connector to go to group of wires or a small box
that has s-video, composite, and audio connectors. This may be
support TV-out. These would not do any video capture.
An ATI All-In-Wonder has both SVGA+TV-out for display and coax for
for capture built into the same one or two slot card. However, this
pokes the video capture data directly into the video output buffer
rather than sending it over the PCI bus. This makes it useless as
a video4linux device for MythTV or almost any other application
that records video. However, the card may still be useful for TV-out
only.
A TV-Wonder card does not have any SVGA connector and does not do
video output. This is supported by the bttv driver (bytesex.org)
and will absolutely work with MythTV. You would also need a separate
graphics card for SVGA or TV-out.
If your card says ATI Rage 128, has a coax and SVGA connector, it
is an AIW card and cannot be used for capture.
I also have 2 usb TV tuners to try including an ATI USB (I've no idea
what model/version) and MyTV2Go ('for Mac' sticker on back). I was
using debian with no success so I switched to Fedora after I found this

You need the bttv driver from http://linux.bytesex.org/v4l2/bttv.html
which should be included with your linux kernel. Google for bttv
to find help with setting this up and testing. Make sure video and
audio capture work before proceeding further with MythTV.
Oh- and am I right that the card with the coax port on it is called a
capture card?
If you go to a computer store and ask for a capture card they may
point you to simple devices to hook up a camcorder. TV tuner card
avoids this confusion.
