Windows Media Center Extender question

  I have an HP Windows Media Center XP computer.  Have just installed
the Linksys WMCE54AG Windows Media Center Extender for Windows XP.

I can play on remote tv set using the Extender tv programs and movies
that were previously recorded by Windows Media Center program.

However, is it also possible, using the Extender, to play movies that
were previously recorded on the hard drive that have "audio-ts"  and
"video-ts" formats?    OR, to play any media that was not recorded in
the Windows Media Center format?

all replies welcomed!   Aaron
