MCEDev are doing some good Media Center development at the moment, and their latest project  is TV Toolbox, this is a 10 foot editor and converter for recorded TV files.

It allows you to edit recordings, convert recordings and define rules to automatically convert just recorded TV shows to a specific format

Looking at the screenshots the application looks very simple to use and is designed specially for Vista Media Center.

Not only is the program an editor of TV files you can also use it to convert the files in to different formats, such as WMV or Zune and all from the 10 foot interface.
