Oh boy. First, whats the make/model of the tv? LCD's have a native resolution (if it's older, it's probably 720p). The xbox 360 will scale the image of a 1080p dvd to the output level selected in the system menu tab. So if you have selected 1080i as the output level of the xbox 360, the xbox will scale (down in this case) the video to 1080i, which may cause a little change to the over-all picture quality. Most HD-DVDs are going to be sold as 1080p because this is currently the highest resolution that HDTVs can display.

Sorry to mention, but the previous post will not work. The output level of the RCA connectors are not going to be enough to power the headphones. You will need a headphone amp, which are comonly available, and a series of adapters to connect the 360 to the headphones. Most headphones use either a mini-plug or 1/4inch jack. Adapters for theses are everywhere. Will you be feeding the audio to the headphones and a television? In which case, you will need to split the RCA connectors (from the xbox) with Y-splitters feeding both the headphone amp and tv. Some headphone amps will accept the RCA line inputs, if not, you can buy adapters that will sum stereo RCA out to mini-plug or 1/4in. The headphone amp should accept either the mini-plug or the 1/4in. Again, all this cable switching will lead to some degredation in audio quality.

Look, I'm just not a dog person and quite frankly I think this will ruin an otherwise great RPG.  A familiar would be much better a cat, mountain lion, panther, monkey - some choice of what you want to follow you around the whole game.  Forcing everyone to scoop up after their dog doesn't sound too fun...just my opinion.  I was looking forward to this game until Sir Peter announced this great new addition to the game.  Any other traditional RPG's coming out for 360?  Wasn't looking for nintendogs with swords.
