I think it's possible, but could not find any prior threads.
I have my new TiVo set up to "Watch One Channel, Record Another (w/Cable Box)". The cable box (SA 4200) currently in use w/ my existing setup, is not a dvr.
Previous to joining TiVo, I was using Cable Co dvr (Scientific Atlanta 8300). I have recordings on the SA 8300 that I would like to upload to TiVo. Is this possible? If so, how? The setup would be temporary, as I'd like to return the SA asap. And yes, I have enough hd space (300gb) on TiVo to accomadate the upload.
SA 8300 dvr box has: rf in/out, 2 rca inputs, s-video, IR, Sata via usb
SA 4200 cable box has: rf in/out, 1 rca input, 1 male svideo input
TV1 has: rf, 2 rca inputs, 1 (mono) male svideo input, ant in
