All of your remote issues can be resolved by getting a Harmony One remote. I use this great remote to seamlessly integrate my Sony HDTV, Denon AVR, Denon SACD, Toshiba HD-DVD, Panasonic Blu-Ray and infinity Alpha speakers.
Plus the Harmony One looks really cool.
For some reason, I've avoided the universal remotes. But the Sammy and Panny remotes are configured so badly that I've been considering getting one for awhile.
