Forgive me if I missed it in my search, but I've got a 5 year or so old 23" LCD TV that can do 720P but only has an NTSC tuner for OTA TV. Is there such an animal available that would allow me to capture OTA HD TV without spending an arm and a leg? From my limited research, it appears that most of the DTV converter boxes are only SD. It would be nice to get HD on the HDTV. My other options are convoluted with either a PC hooked up to it or an extender from my VMC.
