Well, good news!!!!
I received the Impact Acoustics 5x1 HDMI switch and I am happy to report that it works flawlessly with my Toshiba HD-XA2, Samsung BD-P1200, DishNetwork VIP 622 DVR, and Panasonic AE700U.
I can even switch, on the fly, between sources and go right back to where I was with no lock ups or loss of signal.
As a bonus, if you do a search on Impact Acoustics here on Audioholics, you will find a link that provides a 20% discount on top of their already fair prices!!!(till the end of this month)
