your best bet might be an excellent set of tools called 'transcode'.
you will also probably need to recompile your kernel to include modules for the video capture chipset.
You should be able to discover what that chipset is by googling for it.
I own a Leadtek Winfast TV2000XP deluxe and that uses the very common BT878 (I think -it's BT8x8 anyway) chipset,
however on my recent excursions through the kernel I think I recall seeing modules for ATI chipsets (I don't think they use the BT one).
You will also need to include the 'Video For Linux' module, and probably also the module for the sound chipset on it (unless that's handled by the line-in on your sound card).
So basically - you need to tell the kernel to include video4linux support (v4l), and also specific support for the video-in hardware on your card.
then you install transcode, and learn how to use it
(you can find tutorials for that - just google for them, and also read the manpages).
basically transcode takes options that define the input source/file (in this case /dev/video probably - which would be mapped/aliased to the module for the video chipset) and the input format (in this case v4l (video for linux)), as well as the output formats. it also accepts similar options for the sound stream (probably from /dev/dsp if it comes from your sound card - and try using the 'raw' format). there are lots of other options as well but those are the main ones.
transcode is a command line tool so you don't have to worry about your windows environment.
I suggest ripping the video and audio streams as the raw formats (ie saving them raw) and then running transcode again on those files to encode them.
You'd better have a large harddrive for this
otherwise if your computer is fast enough you could try encoding on the fly but you'd be lucky if the results were good (esp with regard to audio sync)
so anyway - just do some research based on these suggestions and I think you will be ok
P.S. you might not like the idea of a command line ripping tool, but it's very good and you'll find that many of the better GUI programs are just frontends for transcode anyway - so you may as well install it now. And you will need to do the kernel stuff to get the device working anyway - unless of course it was automatically set up when you installed your distro, in which case you should see some stuff about it in the output of dmesg.

it seems that people using this card haven't got the tv tuner to work at all...
of course this might just mean that they don't know how to enable support for it I guess... poke around in the kernel - and maybe try kernel 2.6.x
