I have an Infinitv PCIE card on a Windows 7 machine. What I have noticed is that if I have any network traffic, say downloading a file or opening a web page from a machine on my network I am seeing macroblocking and pixelation. i see it on the main PC and on my Echo. I have an all wired Ethernet connection with Gig switches. Prior to installing the Ceton card I have used Moxi devices without any issue. Also, I can stream HD rips from my Unraid Server to my XBMC, browse the internet etc. from another machine without any distortion. Has anyone had similar problems? And if so, how were they corrected?
