Thanks - good to know.
While there probably are better I'll have to say I've had no issues with my Yamahas in terms of how they handle video input/output and I notice from his other thread the OP is using a relatively new Yamaha. I've had older Sony models that mangled the video so not all receivers are created equally.
One poster in another thread specifically cited having Yamaha A/V receivers and got excellent video presentation...but required optical connections for solid audio. That is common to other brands as well.
The newest HDMI v1.4a compatible components (including A/V receivers and corresponding HDMI versioned cables), as well as Blu Ray players, HDTVs, and other devices...handle both well on the single cable. Unfortunately, those are still pretty rare and very new...and most folks don't have them (yet).
