Yup and likely why it's been dismissed or not thought of but AA is a hog and the above uses several algorithms that AA uses and it's hardware based. If it can detect an edge and noise it can be tuned to do AA. The worth less feature you turn off caused me to wonder at all the AA issues others were commenting about as I didn't have them on my 2008 Samsung DLP and it was the very top end with TI video processing. When I connected my PS3 to a cheaper TV I seriously noticed the AA issues in older games.
If you can force developers to support 1080P you can probably get very good performance out of the built in HD Media accelerator to
eliminate aliasing.
