Can someone please explain to me the difference in the 1080i60 output of the Toshiba HD-A2 and the 1080p60 output of the HD-XA2? I'm laking the technical knowledge of how the 1080p24 film is "converted" to 1080i60 for the HD-A2 and 1080p60 for the HD-AX2. I 'm just trying to educate myself on what processing of the 1080p24 happens before it gets to my HL-S6187W 1080p TV. Thanks.
