The AMD chips are much better when it comes to matching the refresh rate to the actual video framerate. Intel graphics have been particularly bad at displaying 23.976 FPS content, which is what most movies are filmed at I believe. Long story shot, die hard HTPC enthusiasts recommend the AMD Trinity chips over the current Intel offerings for pure HTPC playback.
I'd get the AMD myself, thought the A8 is way too much power for what you need. The A6-5400K is very popular for HTPCs and is only has a TDP of 65W instead of 100W (less power, less heat). In fact, you could even get away with an A4. I'll be building a A4-5300 HTPC myself soon.
