.MTS "canon" format HD video to Blender sequencer

wooops I am realizing now I did not try to play it with Blender.
Just that Quick Time player did not show the footage, but I
assume Blender does not play it without its codec, is there
some place on web to get the codec if someone knows ?
camera solve (motion tracking) is what I am after

May be perian.org codecs will help. MTS file very compressed video, it is best convert such files to prores 422 HQ quick time or sequence of tga (8 bit) or tiff 16/8 bit files.
