Please don't post if you don't know what you're talking about...
OK, I'm getting tired of this post so I'll just clear as much up as I can...
VHS/VHS-C - RCA only. A card like Yeti would be fine, even less as you're limited to basically 352x240x30FPS...
SVHS/SVHS-C - More around the lines of 480x480. These cameras tipcially have SVIDEO connections, so something like Yeti said would be perfect.
Hi8 - Basically the same as SVHS...
Digital8/miniDV - Best quality(720x480) a DV card is almost a must as you get perfect quality, and can export back out.
Now the only problem with older analog cameras(anything other than D8/miniDV) is that the signal is totally analog so there's a good bit of quality loose. Also, captureing using analog results in rather large file sizes. DV(firewire) also has larger files, but tends to work better than analoge.
If you do infact have some analog camera, you might want to look around for some card with an onboard compressor. MPEG2 if you wish to burn to DVDs. Don't be fooled, most of them are simply software compression. Expect to pay about $80-200 for a real hardware compressor...
If you're computer is new, you could probably use a software compressor. 2GHz or higher is usally required for the optimal performace, but you still might get frames dropped.
Most cards don't have an output. DV can go back out though your camera which gives you no quality loss. If you can't use DV, you can always use a TV out on your video card, but there's even more quality loss there... Video card outputs are made to cram huge resolutions onto the screen. A normal TV runs at around 720x480, where as a computer is at least 800x600 today...
OK...I hope this is good enough
