My Panasonic DMP-BD65 has the ability to play MPEG-4 AVC/H.264 directly from a SDHC card or from a DVD. I haven't tried it yet, but will soon, as I just purchased an AVCHD camcorder, the Canon HF10. I believe the newer generation PS3s, the slim models, also have this ability, with both SD cards and DVDs. I'll try both after I get my camera (but that's not until the end of March).
Most newer or recently released Blue ray players should be able to do what your looking for - The main thing here you'll have to look for is price - obviously the player that are 69 bucks prolly wont do it.
Also you might wannna just take look online before you go out to the store and make sure it'll play those HD files.
