In the last two weeks I have purchased a Denon DVD A1 and an A1SR amplifier. I have a couple of problems 1/ The A1 has been supplied with the Second Edition of the Denon Link. The A1SR is not recognising the DL signal. As the A1SR DL socket does not have an SE on it I presume it is using the first edition of the DL. Hence the A1 can't talk to the A1SR via the DL. Given the DL is a main part of the reason I bought this combination this is bit of a nightmare. Does anyone know what the situation is with getting the A1SR upgraded to the Second edition of the DL? I really hope it doesn't involve a hardware change..... 2/ My reputable dealer gave me an A1 firmware upgrade for MR and PAL progressive. When I tried this I put the disk in the machine and expected it to load and write the upgrade. However, instead it treated the disk as a CD-R and took me to a directory screen. On the left panel was ROOT and in the right ROOT-0. Pressing enter on either of these had no impact whatsoever on the player. I am a bit loathe to try anything else as my dealer told me if the firmware upgrade went wrong it could lock the DVD player. Has anyone found themselves in this situation? Any words of advice much appreciated..... it's a bit miserable having spent a fortune on this gear and finding I am still miles away on picture and (probably) audio quality.
