But I am curious, how many of us are having problems, and with what hardware. I urge anyone who is having problems to report it to directv's engineering department so maybe they will come up with a fix. But until then maybe we can work together and find a temporary fix that works with our respected avr's.
One of our tasks is working with various AVR brands to secure HDMI certification..
To have market acceptance, an AVR needs to be Plug, Play and Go with the more popular sources of HD components connected by HDMI. Inside the majority of AVRs is a chip called the HDMI repeater, its purpose is to recieve the incoming HDMI stream, route it through the appropriate circuits and then output the HDMI stream to the video display while maintaning its HDCP (copy protection).
When an HDMI product (AVR, source or display) is certified by HDMI orgnization it goes through a lengthy, costly process of component interoperability testing with other brand HDMI products. The AVR is more challenging than a HD display, as the HD display only takes the HDMI signal as an input. Whereas an AVR must transmit back out (repeat) a protected HDMI signal.. The problem here shows up as handshake issue and/or as an exteremely long time for the AV signal to sync up.. The proper solution requires careful writing/debugging and testing of the HDMI software. For the reasons mainly to save certifications costs and delays of shipping
to the market, certain CE brands such as Direct TV, Samsung, LG, Sony, Apple and many set-top boxes including Motorola, Scientific Atlanta do not
have their units HDMI certified...
Read the forums and one can see this problem pops up frequently, it maybe has improved slightly in recent times with more experienced software engineers but it still exists...
