GeCube All-In-Wonder 9600XT 128M/TV/FM
An anonymous reader points to Hexus.net's review of ATi's newest All-In-Wonder product, writing "This looks like a rather nice product if you're running an XPC or similar." He excerpts from the review "It doesn't need an external power source, instead it's quite happy sucking from the AGP slot. The end result? Small form factor PC owners will quite happily be able to slot one into their boxes and run it without an issue. The one slot cooler and cool running RV360 core conspire to make sure heat won't be an issue in those enclosed spaces either."
The 9600 models never needed a molex connector, though the 9800 model did and all products based off the newer cores from ATi.
It's an old part.
If you're looking for a TV tuner card for linux, ignore this. The only drivers for it do not support capture or TV-out.
Etiquette is etiquette. He kills his mother but he can't wear grey trousers.
Not sure if this is what your looking for but, Nvidia's card offers that: "The products will include a TV tuner card with hardware MPEG-2 encoding"
Try the Hauppauge PVR-250 or PVR-350 (or generic versions using the same chipset.) Linux support is fantastic (I should know, I'm the co-author of the ivtv driver) and much better than the ATI All-in-Wonder cards, if you actually want to capture MPEG video in addition to just video overlay.
It's called the ATI eHome Wonder, a MCE2004 class (Connexant Blackbird MPEG2) card:

Not an AIW Tuner+graphics combo, but an individual tuner. It's quite well done. Hardware seems okay and it's cheap.
