Can play cd no problem but dvd just keeps sticking and jumping.
Thought the disc may need cleaning but that makes no difference
Tried several discs. Device is home cinema system HT-DB120
FYIInitially, CD lasers with a wavelength of 780 nm were used, being within infrared range. For DVDs, the wavelength was reduced to 650 nm (red color), and the wavelength for Blu-ray Disc was reduced to 405 nm (violet color).
So the "pits" that is has to read are smaller on a DVD
Is it possible to purchase this lens cleaner in UK as shipping costs seem to be o.t.t. ?
