theres a solution to all this shinannygon! or however its spelt lol.
As far as I am aware, Waninkoko Released a Cios that reads DVD discs of any kind. Anyway Marcan and team are releasing a new Lib for devkitpro that will allow you to read discs anyway without cios.
so what happens is
Someone makes a DVD reading app using the lib, Implents safety feature such as, Readahead_buffer so the laser has to read a bit, have a break, read a bit more so on, instead of on the fly reading. keep the disc spinning at a normal speed, not faster but maybe slower if it dosnt have to keep reading it much.
there we go, dvd is here with safety.
