Hello, I've decided to get a Panamax Max 8 for my new gear. The description says it is HDTV ready. What does this really mean? I get HDTV through digital cable, so is this device compatible with my signal?? I've looked all over the place and everything just says it is HDTV ready... I know you have to be careful what to use because satelitte and cable protectors have different specs. Any and all help is greatly appreciated. Thank You.
