I prefer the Matrox G450 eTV over the AIW personally, but I do not game on my A/V workstation as this card is not a powerful 3D rendering solution. DVDMax alone is an industry leading feature that I wish all consumer oriented video-capture/graphics-accelerators offered.
BTW, I have owned several ATI AIW series cards. They are great products, but again, I have no need for gaming quality 3D for my A/V workstation.
Here is my review of the G-450 eTV:
