I seem to be stumbling onto a rather strange problem, with a windows RDP 6.1 client, if I remote into a XP machine I can play a video through the RDP client. If I RDP into a Windows 7 machine I get a video error. I am trying to setup a VDI enviroment with thinclients that can not be upgraded to RDP 7 client. The VDI needs to be running Windows 7 and needs video with the use of thin clients. Thanks for any help in advance.
