"Great under Windows XP"4.0 starson by denfirecom
Pros: Receives clear QAM, Hi Def Clear Qam, ATSC, NTSC
Cons: A few video grabs when CPU is loaded down.
Summary: I got this after returning a Haupphauge USB DVR (see review elsewhere on this forum). It found all of the clear QAM HD channels on my Comcast cable system. The picture is crystal clear. Made me realize all my other QAM HD receivers that are in DVD recorders do not deliver true HD but upconverted 480p. Time shift works well.
I use it primarily as a window on the desktop but watch football full screen.
I would recommend this product especially those with older motherboards lacking PCI Express slots.
