Hello, I'm rather new to the whole hometheater thing so forgive me if any questions are obviously stupid or easily answered by searching (I did quite a bit of searching but it's possible that I don't know what to search for to get the desired results). I've read quite a few of the posts here about this set as well as a fair bit of information available around the net and I still have a few questions about tweaking the set/using some of the features, and using some of the more advanced features in avia. 1)I have a thread here: /htforum/showthread.php?s=&threadid=154813 where I posted a few questions about the widescreen modes for this set (posting it here b/c I assume it will get noticed a bit more in a thread about this set vs. the thread about progressive scan) 2)How do I use the more advanced Avia test patterns to calibrate this set - I didn't notice any instructions/what to look for/what to change in those tests 3)owners of this set - what are the tweaks you have found to be most helpful in getting the best pq out of this set/anything that you have found to be helpful knowing about this set in general 4)Has anyone found a way so that the guide mode switches audio to the highlighed channel when passing the sets audio to a receiver? (currently I only get audio on the channel I was viewing when I pressed guide, unless I turn the tv's speakers back on and don't pass the audio to my receiver) 5)Thanks much for any and all input!!
