Not directly, only way would be to remove the drives from each pvr and directly copy the recording files converting the format as required. You will need extra software to allow access to the non standard File System on the 9300 at least. Some info on this in this forum.
Basically the answer is NO.
Pvrs can only directly record from their own tuners. Panasonic make hybrid Freeview/Freesat DVD recorders/pvrs. You could record directly to one of those.
