Converting .m2t Files For Use In Final Cut Pro 6.02

I have a number of .m2t files captured on a PC using Sony Vegas as .m2t files. I know that I cannot directly bring these into FCP6 nor Compressor 3 and I am seeking the best workflow for converting these .m2t files for editing in FCP6. One workflow that seems to work is to bring the .m2t files into VisulaHub (which imports them nicely) and converting them to MPEG-4 files. These MPEG-4 files can be brought into FCP6, but when I apply them to the timeline and allow FCP6 to match the sequence settings to the file format, I get a red render bar over the files. However, when I select "Render All) the render is essentially instantaneous and I can play the files in real time in FCP6.

My questions are does anyone have a better workflow for converting .m2t files into a format that can be (a) edited in FCP6 and does not require a second render just to get them to play in FCP6?(b) Is there anything wrong with the workflow that I have described above?

Thank you in advance for any help or advice you can give to me.
