This second TV-tuner product from AMD is more of a traditional product in terms of what we're used to see from ATI and the TV Wonder 650 is an upgraded version of the TV Wonder 600.
It has support for ATSC and ClearQAM digital TV (Free-to-Air and cable based) as well as having support for analog TV. With dual tuners you can watch one program while you record a second.
The TV Wonder 650 also supports S-Video input and it comes with the same PVR software as the TV Wonder 600 USB. The TV Wonder 650 will be available in PCI and PCI Express versions and should be available some time in September.
