Just bought a yamaha s550 and opted for the multi-region modification for an extra £10. So the machine arrived and I expected it to be multi-region out of the box. But no, there was a sheet of A4 paper with the 5 steps needed to carry out this mod. using the remote. There was also a caution warning on the A4 sheet advising "follow these instructions carefully as misuse of this procedure could result in a void of the warranty and possible damage" Now I know it's only a tenner but i can't feeling ripped off. Do the company who sold me the player just trouser the £10 or do they pass it on to someone else? Have they had to pay for this info?
