    So my friend gave me a copy of his movie "nightmare on elm street 2010"
    He went to my house to see if it can play on my ATV before he will buy..

    This is my first time to play 1920x800. MosT of my movies were ripped via handbrake. So they are 720p for sure.

    We were very surprised! God damn... There is no stutter and at the same time I am downloading heavily some stuff on Mac mini. The sound is spectacular! And most of all the picture is so nice. Now all my movies that was ripped via handbrake look amateur.

    My Internet subs 20mbps
    Router netgear 3400 set to 5ghz dedicated for ATV, Mac mini and iPad only. The rest iPhone 4 and all other laptop are on 2.4ghz

    Get the most out of your ATV. Find a good router and Internet speed will do it's job.

    What does the broadband connection have to do with the movie playback of a local stored file?

    Its because for the streaming. The movie was stored on Mac mini and not on apple tv. I have the new one and not the old...

    If the movie was stored on your Mac mini the internet never gets involved - it just streams over your local network

    What is the file size of this movie? The bitrate? Was the audio dts or ac3? Thanks! This is reassuring!

    Most router's will do that easily. And you're not streaming 1080p there, that's just above 720p (It's 800p lol).

    The XXXp is the amount of pixels vertically.

    My router can stream a BluRay rip of Avatar to my AppleTV Without stutter, most 802.11g/n routers should do it perfectly..

    The bitrate is the most important part. High-quality 720p can easily beat low-quality 1080p in bitrate thus it's more important to talk about the bitrate as resolution can often be misleading.

    Bitrate is everything. More than likely the "sample" he's watching cuts out the black vertical bars; it depends soley on the aspect ratio of the movie, and even then, the amount of pixels isn't paramount.

    All things being equal, more pixels are better, but more pixels require more bit rate to avoid compression artifacts. So, a lower resolution picture might actually look better than a higher resolution picture at the same bit rate -- if the bit rate is so low that artifacts are an issue.

    1920x1080p is 1080p. Widescreen films need to either have black borders on the top and bottom giving you a 1920x800p picture, or in anamorphic mode with rectangular pixels, then a 1920x1080p could use all of the pixels that the BluRay format offers and still maintain the original aspect ratio, but the scaling necessary to fit that picture on a 1080p set would waste that extra resolution -- thus, they do not bother with anamorphic BluRay.

    However, with 720p handbrake encodes of BluRay material, you can use the anamorphic setting to preserve much more of the BluRay resolution. A 1920x800p widesrceen movie would normally convert to 1280x533p. Some consider that 720p, but it really is just 533p -- just a step above a well made DVD. With a custom anamorphic setting you can encode the same BluRay movie at full 1280x720p. The rectangular pixels simulate a resolution of 1728x720p. That preserves 90% of the original BluRay's vertical resolution instead of just 66%. So long as the bit rate is sufficient to keep the compression artifacts in check, this method results in a superior picture.
