Did you try setting the Yamaha monitor skip function to yes in the advanced menu? That might help with both problems. I don't think we used a composite recently with a Yamaha so it is good to know if that is a problem. Does your source have a 0 or 7.5 IRE option, or blacker/ lighter black level option? I'm not sure what you are using as a composite source.
Just FYI the Yamaha is a certified HDMI/ HDCP unit, cable boxes have not submitted for this certification and they are often the cause of this problem but everyone blames the other devices in their system. TVs are often the cause as well as they often report incorrect EDID information back to the receiver/ source, they receive a 480i signal over HDMI but still to use HD settings instead of SD.
You need to find a solution that will work for you and for most people this might take some trial and error, causing frustration. Unfortunately, without testing equipment the consumer is at a loss to know which products are behaving poorly under HDMI/HDCP protocols. HDMI continues to be a problem for consumers, installers and integrators.
Thanks for the heads up. After you mentioned this, I see this is a huge problem with my Motorola DCX3400 Comcast DVR. Many problem reports all over the internet with the "EXACT" same problem I'm having with old and new Yamahas, Denons, Sony ES and Onkyo. Weird that when the Box goes straight to my LG 47LW5600 TV, the resolution stays at 1080i and never changes. Also it's scary that those reports were started over a year ago and Comcast/Motorola never fixed the problem.
Unfortunately Yamaha confirmed that my A710 was defective. Tier 2 hooked up their A710 with a Bluray composite video connection to the receiver, then the A710 receiver's HDMI output to a Panasonic TV. Then they hooked the composite output from the Bluray player straight to the Panasonic TV, bypassing the receiver. They said the "composite video" signal through the Yamaha was not washed out and blacks stayed the same along with a better picture from the upconverted resolution when compared to the composite video that was sent straight from the Bluray player to the Panasonic TV.
So they are getting a better picture that is not washed out as the picture I'm getting. They said this obviously must be a defect with the conversion hardware.
Right now I have so much going on in my life, I wish I never bought the Yamaha as this is just a big pain in the @ss right now as I simply don't have the extra time to mess with this thing, sending it back, and reconnecting my Denon AVR-3803 back into my system.
Thanks for the help in sharing this resolution problem. I may have gone through a lot more trouble had you not mentioned this, Thanks, I really appreciate it!
