I have a Digihome 160 with software v4.4(UK). I have downloaded the relevant files to upgrade to V4.9 and change to the twin record version. (Two unzipped files named single_record_v4.9.bin and twin_record.bin which I hope is as it should be!). Am I right in assuming that the twin_record file includes the 4.9 update or do I need both? If both are needed can I transfer one and then the other in one session or do I have to transfer one and then "use" the box before transferring the other? It appears to me that the Scart sockets are not all that securely attached and I want to avoid unnecesssarily removing/inserting the plugs.
