Thank you for reply.
I'll have crashes when I watch any movie using advanced movie selection or enhanced movie center and then goes back tlll channels. Duo hangs directly and reset. Then I get no sound and I must reboot it. Then freezes again and I must press the back button to start a duo again. With BH 2.1.2 works perfectly, but 2.1.3 and 2.1.4 major problems. I removed the AMS and EMC, but it happens again when I change channels.
