What do you want to do with the card? The answer will vary.

i had an analog card from prolink with a Conexant CX23881 (philips)
& it was very good but it lacked audio inputs which obviously is somewhat subject to A/V de-sync.

Anyway it requires a good cpu to fully enjoy this type of card
2ghz minimum

i don't know about the cards with Phillips TDA8290,TDA8275 chipsets

Currently i've got a similar card than my previous one from prolink except it's got audio inputs+fm.it's from terratec (cynergy 250 pci)

same quality(10bits) and more stable
So far,so good

Conexant CX23881 , supports macrovision detection ... bad if recording commercial vhs .

Phillips TDA8290, TDA8275 are linked to SAA7133 video decoder .

FlyVideo 3000 series was first to support stereo audio caps utilizing the SAA7133 chip , can be tricky to setup for vdub caps under xp , no issue with macrovision .

I had one of those pains before , then ms screwed up with xp , till they released a patch for midi security issue which caused the whole "no caps" problem for many devices , but good linux support now .

A/V sync is an issue with pc setup , not the cards fault ... never had an a/v sync problem , even a p3 800 intel can do it without problems using a suitable compressor for video at full d1 resolution .

Asus v3300 / v6600 vivo's were a lot better .

The higer the noted "bit" of chipset chosen , the better the picture quality ... aim at 10-bit .

Quality is assured , provided you pass the audio to the linein on pc sound device , and not the capture cards audio input ... if it comes with an audio pass cable ... throw it in the bin asap and forget about that crap ... it will cause picture distortions in caps like snow / static .

That is of course , you want the clearest caps available ... if not , use the audio pass cable ... you'll see what I am talking about .

Forget about those damn inbiult tuners , there utter rubish in all devices ... grab video and audio from a vcr , as the vcr is a superior tuner and will split video / audio .

You might need one or more other cables to complete the hookup , such as a stereo headphone to 2 x rca cable ... for connecting vcr audio output to pc linein .

Use the remote for vcr to change channels , and set caps program to VTR mode only .
