I want a list of known problems with dvd players?

ITV Digital was replaced in late 2002 by Freeview, which uses the same DVB-T technology, but with higher levels of error correction and more robust (but lower-capacity) modulation on the "Public Service" multiplexes in an attempt to counter the reception problems which dogged its predecessor. Rather than concentrating on Pay TV services, Freeview uses the available capacity to provide a free-to-air service that includes all the existing five free-to-air analogue terrestrial channels and about twenty new digital channels. All services are transmitted in SDTV mode.
