Video first - connect the video out of your VCR to the composite video in on your tv card (I expect this will be a phono to phono lead).
Audio - You will need to get a cable with 2 x phono on one end (or 1 x phono if you only have a mono audio out of your VCR) and a stereo jack plug on the other end (you can get them on e bay) connect the phonos to audio out on your vcr and the jack plug to line in on your tv card connect a separate connector from the line out on your tv card to your speakers.
When you play a Video make sure you select the appropriate channel on your VCR (usually one of the AV channels)
Software - you should have some software with your TV card try it first and if its ok all well and good - if not (and many in my experience are pretty basic) you might want to consider purchasing a decent one. I use and recommend video expression 2 from arc soft.
make sure that the line in audio is enabled for your sound card (a common oversight) go into control panel select sound then select volume and ensure line in is enabled.
Once you have cracked the above - you can then burn to CD using Nero.
One other thing the video you capture will probably be in avi form - this is incredibly memory hungry so make sure you have plenty of hard drive space; adittionally you might want to consider converting it from avi to mpeg 1 or 2 before you burn this will do 2 things, 1 it will be quicker to burn and 2 you will be able to store it much easier. hope this helps post back if you want more but offline now till about 1800.
