The old Hitachi HTDK170 suddenly stopped working recently. For once a device of mine failed just before the guarantee ran out, rather than just after! Argos were very good about replacing it - it only took a few minutes and what's more they gave me an improved version - the HTDK185!! Not only does the new player have a built-in Freeview decoder, I discovered today that it recognises miniDVDs! In fact it was the same miniDVD that failed to play on the old HTDK170. The new player even put up a graphic saying 'miniDVD' when I inserted the disc.
