Jitter is a known factor using certain input/output interfaces(SPDIF), but it has never been proven to be a factor with HDMI. As the signal enters the HDMI cable it is encoded with transition minimized differential signaling. That is the original signal(down one wire) plus a inverse signal of the original(on another wire). When they get to the destination interface(the receiver) these signals are compared, and any differences corrected. SPDIF does not work that way, it just transmits the signal through the cable with no protocol for correction of the signal. The red book standard does not require block-accurate addressing, but HDMI TMDS does.

If jitter was really a big problem with HDMI somebody would have tested and published such a fact. It is easily measured, and we would have examples all over the net. This has not happened, so I am somewhat suspect of claims of jitter over HDMI. We have seen examples of jitter on SPDIF connection everywhere. White papers have been published, examples visually shown, and the effects can be heard which is why re-clocking protocols are usually incorporated in external better quality DAC.
