The Wii was the first Nintendo console to use a non-proprietary disc format. Even with the Wii U on the way, the original Wii remains the only such device from the company, though the new system is clearly capable of reading the DVDs to which Wii games have been pressed. Both of these consoles, however, despite their capability to read this format, lack the ability to play DVD movies. The Wii U, which uses a proprietary disc format with a storage capacity comparable to single-layer Blu-Ray discs, also cannot play Sony’s homegrown format.
