Can someone please help me ? I have a 42" Sony Bravia LCD Digital TV, a Directv HDDVR model# HR20-700, and a Sony DVD/VCR HD recorder model# RDR-VX515. How do I hook them all up to record live TV in HD, and also record items I've saved in my HDDVR in HD. Sincerely, Kathie... P.S. Thanks for any and all help.
