As this was posted in the HDR-1000S section, I presumed the OP wants to play back recordings made on a Foxsat through a HDR-1000S. Post 3 seems to indicate he is aware of the difference between HiDef and StDef, or at least that is how I interpreted it.
Thank you all for your reply's. Yes as Black Hole says I do know the difference between Hi Def and SD. Graham I have CF installed on my HDR-FOX T2 freeview but not on my Foxsat HDR in fact did not know I could. I have a large amount of files for instance all the Wallander files transmitted on BBC 4 on a usb external disc so would not want to be unable to watch any of the programer's on this drive again.
