There's a firmware update for RX-V1800 and RX-V3800 to solve the DTS-MA bitstream popping sound, the firmware was released on 13 March to solve this issue. A couple of titles were affectly, namely, The Fly, Chronos, Fantastic Four, Flyboys, etc on BD and Eagles on HD-DVD. Not sure whether the firmware can be used on our local RX-V1800, I got no confirmation on that yet.
Another issue that bugs me is the RX-V1800 and RX-V3800 will process the HDMI signals and causes clipping issues. It will process a 0-255 Full RGB signal to 16-235 RGB Video signal, the XBOX 360 and PS3 supports Full RGB signals as well as certain Blu-Ray players and all HTPCs as well. I've asked my friend to check with Yamaha whether this can be fixed and what's the impact if it can't be fixed as my Bravia 400A can support Full RGB signals, I've tested yesterday. It's a big concern to me.
The DTS-MA popping sound via bitstream also affects Onkyo's 605, 705, etc as well and they have more serious problems, lip sync problems via HDMI for upconverted video signals. Seems like Denon and Marantz don't have DTS-MA popping issues but Denon has macroblocking issues when upscaling SD sources. Damn ....... veli headache.

I've read about that. It's the DTS chip inside the receiver that's causing the popping sound. Both Yamaha & Onkyo used the same chip. Do you know where to download the firmware? Though actually for PS3 users, should not be worried, because the signal received is PCM already, the only processing within the receiver is only by the DAC.
The lip-sync problem is only well-known for Onkyo only, not Yamaha.
About the clipping effect, in the manual itself it's stated that the receiver doesn't support full RGB, signals from 0-15 will be clipped. I noticed loss of details in dark scenes. But that's why I used YPbCr instead, I never bothered about RGB anyway.
Get the one that suits you most, the one that it's shortcomings is more tolerable to you, and, of course, versus your budget. The popping sound won't affect you if you're using PS3, and even that can be fixed with the firmware update.
I guess it's obvious huh, I'm also a Yamaha fanboy.
