I bought this HU the other day and am going to install it in my 05 WRX. Installing is not a problem. The websites shows that it plays DVD's, but does anyone know if it plays DVD +R/RW and or DVD -R/RW's? I know it'll play the standard DVD's, I was thinking more along the lines of burning an MP3 DVD on either a + or -. If anyone knows or has tried it, that would be a great help.
