thanks for the reply's....First...I'm using an iTach RS232 controller with iRule.. I didn't know I had another choice...it's what iRule recommended me to get! I do match the rate with the Casa and iRule. I did use the highest rate...at first..but when it started to freeze, I lower the rate. It's at 4800 now. I think I have Echo status set to 1. I DO use feedback...so I guess I need to move that to level 2. It has been working so far..the feedback anyway...I just use the volume, and surround status for feedback.
I just read the post about waiting 4 seconds after power up, before sending another command to the CB. That I'm not doing...so I will fix that now..and maybe that will help the freeze issue?
The handshake issue with HDMI, only happens with the media player...not DirecTV, which is HDMI as well. But, when this same player, which I've had 2 years..was connected to my old Marantz pre/pro...I never had a problem.
The pops in the surrounds....I hope will be addressed soon with an update.
