I currently have a Pionner VSX74 txvi and may need to replace it in the near future for 1080p switching. I really like that the Pioneer will allow matrixing of all 5 channel inputs to 7 channel. If I remember correctly there have been some receivers that wouldn't allow this with certain inputs such as PCM or DTS HD, etc. I seem to remember hearing that many of the Onkyo's had this limitation with DTS HD MA. Do they also have the limitation with PCM. It can be very hard to find this information out ahead of time, so I thought I'd ask here before I start looking. So my question is are there any recent receivers that won't allow PL11x matrixings with certain 5 channel inputs? I'm interested in the 500-1000$ range receivers.
