avchd is not blu ray the main differences are in the sound apart from the lenghth of footage that can be put on blank discs,you say you record 24mbps avchd if that is on disc i am surprised as i was under the impression that 16 mbps was the maximum that can be recorded,that is what my avchd discs are when i burn them but my blu rays are around 26mbps

Yes and no. Yes, there is a difference in that AVCHD is a defined format that uses H264/AVC and may use AC3.

No, in terms of image quality both should look the same IF the same quality encoder is used. That may not be the case.

Can you record 24Mbs on a red-laser dvd. Since the upper limit for red-laser is 25Mbps, the answer is yes. Can you find software that will do this -- you'll have to look. Most top out at 16Mbps.

This is interesting. You mean for playback in a standard DVD player right? I thought the maximum amount of data that DVD could playback is 9mbps, hence all of the encoding software I have used tops out at 9mbps.

NO -- AVCHD can only be played on a BD player.

AVCHD will play on PS3s and some blu ray players.
