Hi guys I've been searching a lot but without conclusions. I have an old 2ghz macbook with 3gb of ram attached to a hd ready tv via hdmi to dvi cable+mini dvi adapter and when playing a bd 720p rip there's a drop in frame rates when the bit rate is higher. I've tried with both vlc and qt with the latest perian, cpu load it's about half way and I have no problems in a single monitor setup. What could this be? The cable setup? Do you guys have any of these problems? Thanks.
