Im wondering if this is just my house, the cable company or what is going on. The volume to my TV seemingly only half of what it should be on my digital cable channels (but only on some, typically those over channel 100). Cartoon Network for instance, volume is fine, is loud at say volume 50, but on say HBOHD, i need to have the volume at 100 for it to be audible. This has happened only on the top floor of my house on two different TVs with 2 Different Set top boxes. WTF is going on? Comcast fault? Home Wiring? Ive about ruled out the boxes and the TVs. Please advise. if any difference ive run it through S-Video and its currently on Component now.
