The display device is unrelated.  Any frontend capable of playing back 
HDTV recordings at HDTV resolutions is capable of playing back HDTV 
recordings at SDTV resolutions (save some that may be using broken video 
drivers that don't do proper downscaling--but even then, it's just a 
matter of getting a better-selected-for-MythTV-use video card).
