There might be a lot of very similar cards out there.  

I thought that Werner's card was a clone of mine, an MSITV at nywhere A/D, 
but mine does not support using both tuners at the same time.  It seems 
that a very similar card does.  

On this site;
http://global.msi.com.tw/index.php?func=prodfaqanswer&faq_no=1599&prod_no=623&maincat_no=132&cat2_no=261&cat3_no=
it says,
	TV at nywhere Duo: 
 	Same as the A/D, this card also support the most advance 
	PIP-picture in picture, and TWIN-one analog TV channel and 
	one digital TV channel side by side. Once you plug both 
	signals, you don't need to switch between 2 signals.
