I have a 42 Inch TV and I am wondering if you can really tell the difference between 720p and 1080p while watching movies. Reason I am asking is b/c I currently have a Mac Mini HTPC on the 42 inch, but I also have a 32 inch in the bedroom. I have been thinking about converting my content to the apple tv setting so I can get it for the bedroom and be able to watch it in there. If I convert my content I will be deleting the current content I have, so I will only have 720p mp4 files. Let me know what you think.
