No issues with up to 10x HDTV streams. With 12x it did start to have some pixelation though that could easily be network packet loss as 8x of the are from network tuners and this system is a low power AMD Zacate (review pending) with a crappy Realtek network card. Realteak, nForce and Broadcomm network cards are the bane of my existence at the moment.
