Thanks you, that explains it vary well.

Quote: .....and requires a Blu-ray player.

This is stated often but is not true. Panasonic DVD recorders play AVCHD discs no problems. There may be other DVD recorders/players which can also play them. Panasonic SD9, Panasonic TM700, Panasonic SD600, GoPro HD Hero.

Some DVD players may be able to play them, but it is not part of the DVD standard, so one shouldn't expect them all to play the disc. I hope more will support the format. __________________________________

Blu-ray disc — AVCHD video, recorded onto Blu-ray disc can be played on any Blu-ray Disc player.

PS: For sure regular DVD players won't play AVCHD discs until and unless they support AVCHD playback.
