I would advise getting a tune up disc. You wont regret it. I read a review that recomended "Home Theater Tune Up by Sound and Vison". I found this disc online brand new for $16.55 and it has been great for a guy who is new to all of this. It explains how to use your SPL, how to tune your TVs color, contrast, tint and so on, plus all the audio test you need. I noticed a considerable difference after I finished going through the disc plus it helped answer many questions I had. It also has several kewl THX, DTS and Dolby video clips that are great for quickly impressing everyone with your systems performance.
Regarding the sub, it explains in detail how to calibrate this most difficult part of the whole process.
Another thing I found out is on the Pirates of the Caribean video, if you go to the THX selection in the audio menu, it has all the audio and video calibration test screens and tones. The tune up disc is still better I think, especially if your new like me.
