I bought the new Comic Strip DVD box yesterday from my local Tesco, and popped disc 1 into the player in the evening to watch "Five Go Mad In Dorset". As the player (Denon 3910) spun the disc up as part of the loading procedure, the player started making a horrible loud buzzing noise and vibrating, which only stopped when I ejected the disc. Tried again - same thing happened. Tried disc 2 in the set - worked with no problem. Tried disc 1 on my Panasonic portable, and I could feel the player vibrating violently while the disc spun - again, the player was fine with disc 2. Ho-hum, thinks I, duff disc - possibly the hole not quite in the centre. Took the set back to Tesco and got a replacement this morning, and that one is no better. Of the 4 discs from it I tried, 3 cause this very nasty vibration on two players I've tried them on. Other discs seem to be fine - it just seems to be some of the discs in this set that cause the problem, but it is really not good. Has anyone else had problems like this with this set? Have I just been *really* unlucky and got 2 bad sets - is it worth trying another exchange, or shall I just get my money back on the grounds that they all do this?
