Okay I am confused about what types of programs I can record at one time. I am running in Single Mode. I have an OTA hooked up too. Tonight I saw that I had two shows recording at the same time. Both were HD Locals from the Sat. I could not switch the an SD or HD channel without turning off one of the timers, BUT I could watch something from the OTA. I thought you could: Record 1 HD Program Record 1 SD Program Record 1 OTA Program All at the same time BUT It seems that I can Record 2 HD Programs and still watch/record OTA all at the same time.
