When bringing .MTS files to my timeline, I find Vegas 9 to be 
extremely slugish.  I've edited different types of HD files in the past
and not had a problem.  How can I work around this?  Is there a
parameter/preference that can be adjusted to allow the program
to read the files with more precision?  Currently, i can barely play
through the timeline - the playback drastically jumps and skips.
Any ideas?
thank you.....
