I got myself a free tuner card after salvaging it from a relative's old PC after transferring their data to a new box and this was what inspired me to give MythTV a go in the first place. It was a bit of a challenge getting it to work, so I thought I'd publish what I did in case someone comes searching via Google and finds this info of use.

The TV card has the following chipset markings:
Conexant
fusion 878a
25878-13
E32731.1
0024 Korea

The tuner has the following:
LG TAPC-i701p
(It's a PAL tuner)

The PLL crystal has markings indicating it's 28 MHz

On the circuit board itself:
PMC 878TV (rev.3f)
(PMC = Prolink, so it's a Prolink 878TV rev.3f)

Modprobe can't auto-detect through the firmware as there's nothing there to check, so you have to provide the parameters manually. The following settings worked for me:
modprobe bttv card=37 tuner=26 pll=1

You can find more details on what these settings mean at the BTTV howto:
http://www.tldp.org/HOWTO/BTTV/index.html

To make these permanent, edit "/etc/modprobe.d/aliases" and add the following line: (Without the quotes, obviously.)
"options bttv card=37 tuner=26 pll=1"

Hope that helps someone!

Sorry, this should be in "Tier 2" rather than "Tier 3" as it provides the info to get it working. Can a mod move the post, please? Thanks!

What about the rest of the system? These recommendations are only as useful as you make them. Please see the sticky posting: http://mysettopbox.tv/phpBB2/viewtopic.php?t=10956

Appreciate what you're saying tjc, it was purely a "if you have a PMC 878TV (rev.3f) tv card with the listed chip/tuner markings then these are the settings for it" post, with the assumption that the rest of your setup worked.

For the record, here's the specs:
