I have a Panasonic SC-PT865 wireless home theatre connected to my Panasonic TH-42PY800AZ TV via an HDMI cable.

I also have Sky Hdi connected to the same TV via another HDMI cable.

I have the audio from the TV to the home theatre connected via RCA cables.

When I play DVD's the volume and audio quality levels through the hime theatre speakers are excellent but when I am watching normal TV the volume and audio levels through the home theatre speakers are much lower.

Can anyone help please?
