To edit AVCHD or M2ts you need a very strong computer (with a quad-core processor). It is easier to convert the files to a mpeg2 format. This can be done with the export function in Video deluxe. First you need to drag the file on a timeline and then you can export them (File-menu, export files) in mpeg2 in the same resolution. Used the conveted files to edit them. After finishing editing you can export them to any medium such as a the SDHC card.
To play HD-video you need a Blu-Ray player or with some standalone player (i.e. Western Digital media player) you can play from harddrive USB-stick or SDHC on a HDTV. Of you can read dutch take a look on our website www.video96.be.
I publisched some articles about HD video formats.
