BTWinCap is an alternative Windows WDM driver for those with BrookTree/Conexiant based capture cards. This is a wonderful enhancement to those of us who have either unsupportted, or poorly supported hardware with newer systems (Such as drivers for Windows 98 only).

I’ve discovered that my MediaLand SuperTV is the same as a Prolink PlayTV Pro (model 8E). I would use their given drivers; but they seem to have introduced an intentional bug. This bug causes the card to reset once it gets an open/reopen request; the practical upshot of this is that you can no longer use your card for capturing with software such as VirtualDub.

The BTWinCap driver solves this, by not having these [intentional] problems. Below, find my “BTSpy” formatted file which allows the card to work perfectly well with the TV, SVideo, and Composite components; but the FM radio function does not currently work. I’ll try debugging the issue with the FM tuner in the future.

This is a working profile for btwincap
with the Medialand SuperTV, AKA Prolink
PlayTV Pro (Series 8E). The video and
audio works perfectly for the TV. Svideo,
and Composite inputs; however the Radio
does not; neither are any BookTree
enhancements available with VirtualDub
or DScaler.
