Need Video Quality Help

[trekdude]

I need some help with my new Pioneer vsx-919 receiver. After getting the receiver about one month ago I have noticed the video quality of the comcast HD is better when the cable box is connected directly to the TV. The HD picture looks slightly less clear when connected via HDMI through the receiver.

At first I thought it was just me, but my wife said something about decreased video quality over the weekend. I never mentioned my concern to her before.

The VSX-919 does not upconvert, but I'm sending a HD signal so don't need it.

I'm using bluejean hdmi cables for all connections.

The TV input settings are the same for receiving video directly from the cable box or through the pioneer receiver.

I expected the video quality to be the same regardless of whether the video is going through the receiver.

By the way, my Sony TV only has stereo outputs. I though about outputting the Comcast audio from the TV to the receiver, but guess that won't wonk.

Any thoughts or suggestions? Buying a more expensive receiver isn't really an option in my situation.

All suggestions will be greatly appreciated.
