I have just bought a Pioneer DV - 454 - very similar to the 350. The machine is supposed to play all disks. I have tried both VCD's and SVCD's and when I put them in the machine is says VCD on the display and also on the TV. However, when I start to play I get three images fiickering up and down on the screen. The sound comes out o.k. though. Any suggestions as to what the problem is ? It plays dvd's and MP3's o.k.
