I can't play dvd's when I connect my laptop (HP dv7 series, Windows 7 Pro x64) to a TV (a Toshiba I think) via HDMI. If I disconnect the HDMI-cable I can play dvd's in both WMP and VLC as normal. When I connect the HDMI-cable I can see my desktop on the TV but I can't play dvd's in neither WMP nor VLC. Both WMP and VLC acts as if the dvd's are a corrupt or unsupported file, except for the lack of a warning.
I can't really figure this out so pls help.
