I got a new Liteon BD player for X-mas.(401s) it came bundled with Power DVD 7.1 Ultra and come to find out that it is incompatible with my 4850ATI running under XP due to it's unability to see the copy right incoding on that card. It tells me I have to up-grade to Dr Ver 7.1 when I am running 8.1? Anyone know a workaround for this as I would like to vew some BD movies? Thanks
