Tim, you're right. You don't need to worry about the picture. The Panasonic plasmas have decent scalers built-in so the I'm sure the PX80 will do a great job with a 1080p signal. Like you say, all those receivers will pass the picture signal through untouched. The EP30 is limited to PCM audio through HDMI but this is not a big deal. Very few HD DVDs have DTS-HD Master Audio (it's becoming more popular on Blu-Ray) and most carry either Dolby Digital Plus or DD TrueHD, both of which the EP30 can decode and pass through to the amp as PCM over HDMI. The point is, as long as you have an amp that can accept PCM through HDMI you WILL get HD audio. The Onkyo 605 can do this, the 505 can't. I would definitely go along with what tom83cat says about waiting for the 606. If you can afford it go for the 606 when it's released, otherwise pick the 605 at a reduced price. I can heartily recommend the Q Acoustic package to go with the Onkyo. Apparently the newer 1010i package is even better and worth getting if you can find it for a good price. Can't speak for any of the others.
