Hi all,
New user + new HT owner here. Any and all help is greatly appreciated. If I happened to post this in the wrong thread, please point me to the right one

Ok, here's the concern:
I had recently purchased an Onkyo TX-SR605 receiver after reading the many reviews and comments here. My issue is that when I'm watching the HD channels, the volume sounds like it's really low. For example, if I set the volume at, say, 30 th SD channels sound louder than HD channels. I have DishNetwork Vip622 DVR connected to the receiver using HDMI (v. 1.2 cable) and have the Dolby Digital option to output DD/PCM with RF Mode compression.
I'm not sure if it's something I did wrong or if this is an overall issue. Here's my connection setup:
Speakers: JBL SCS500.5 package
Connections:
1) DishNetwork Vip622 DVR connected to 605 via HDMI
2) DVD player connected to 605 via HDMI
3) HDMI from 605 to my plasma
I don't have the level calibrations set by the Audessy auto-setup with me right now as I'm at work, but I can post them later if needed. One thing I did notice is that the Sub's level is set to +12db (I think). I had the volume on the sub turned up to half-way point before running the setup.
Thanks for your help in advance.
