I'd have to rate the MyHD card higher than the HDTV Wonder basically because:
* it is hardware (MyHD) vs software (HDTV Wonder) with hardware being far less intensive demands on your system.
* Native Transport stream capture (MyHD) vs Proprietary real-time encoding (HDTV Wonder) ATI's VCR format is easy to transcode to friendly full resolution MPEG-2, but still requires an extra step and requires more resources.
* Display connectivety. MyHD can output directly to my HD display bypassing the PCI bus using VGA (DVI with the upgraded card and optional daughter card) HDTV Wonder relies on the video card for output.
* Mature Product MyHD has been around for years, HDTV Wonder was just recently released.
Doesn't mean HDTV Wonder is bad..its not, very good actually for a new product and it has a far more reasonable price. ATI has a much better bundle including a better remote, an antenna that actually works. Features like MMC support, timeshifting and burn to media are also not available with MyHD. HDTV Wonder will undoubtably get better with time, I'm not sure I could say the same about MyHD, but right now, IMO, the MyHD is the superior product even at the higher price.
