    Yes, a DVD is only 720 wide. If you use ACT1, it will stretch the video upon playback. Now if the movie isn't the same AR as the Droid screen, you will of course get black bars on playback too (whether H or V).

    Encoding movies to 848 is best left for HD formats, like Blu-ray.

    You are barking up the right tree

    The first thing is you need to remove the actual borders from the video. Supposedly Handbrake does this automatically, but I dont use it, so I am not sure if it does or not. Basically play the video on your computer (quicktime) and if there are no black bars, it did the job.

    Second, when you play a video, the Droid will scale the video to either the full width or the full height. Your 720width will be scaled to 844 (actually 854) for a widescreen movie, or for a 4:3, it automatically scales the height to 480.
    To make sure you do not end up with black bars, you have to perform some calculations.

    Say your DVD video without the black borders is 720x360

    When you play this on the Droid, it will be scaled from 720 to 854, so the height will be 854/720 x 360 = 428 or something close to that. this is less than the 480, so you end up with black bars of 26 pix in height on top and bottom.

    So to get your cropping right, you will have to cut off something off the sides of the video (as explained in the article linked in my previous post)
    start with the height 360, and find the scaling applied to it to make it full height
    480/360= 1.3
    Now multiply the width (720) with this to get the value of the width if it was scaled
    720 x 1.3 = 936
    since we want the width to be 854, we will have to cut off the sides, so 936 - 854 = 82
    because we want the middle of the movie, we have to cut off 41 from each of the sides, but because the video is scaled by the player, you have to divide it by the scale factor. so 41 / 1.3= 30 (close)
    So in your conversion tool, you have to enable the black bar removal so the actual black area is gone, and then adjust the crop width to re3semble the 30 width that needs to be substracted from each side.

    Of course this differs per movie.

    You're an idiot. Did you not see how old this thread is? Rockplayer wasn't available when thiswas started.

    Thank you for your input

    I hope you realize you are reviving an old thread, in which its last post was dated before RockPlayer and vPlayer were available not counting the availability of VLC for Android next month.

    But, while there are avi players out there, these files are not the "Ideal Video Format" (this thread's title) for Android devices. The Droid and just about all Android-based devices released since, have HARDWARE support for MP4 files.
    While these other players can play a multitude of video files, including avi and MKV, when non-"ideal" video files are played, the processor is used more, resulting in either playback issues, lower quality (divx compression is not as good as H264) and usually higher battery-drainage when playing files.

    Thumbs up HandBrake 0.95 is out!

    The new HandBrake 0.95 is out. I have attached the Droid profile I created to use with it. Works great. (Keep width of a HD movie at 848, or 854 if you relax the block size.)

    The two files in the ZIP archive are the same profile, so pick one depending on how you want to import the settings. The plist is for importing the profile within the HandBrake GUI. The XML file is if you want to copy it to the application folder (I prefer this option)

    On XP, that would be:
    C:\Documents and Settings\<username>\Application Data\HandBrake\

    For either preset, the only thing you should need to change is the Constant quality RF or the Bitrate depending on your quality or size needs. You may also want to make sure the file is saved as an MP4 with the .MP4 extension.

    Enjoy!

    There are many different ways to get your movie or video converted over to a format that will work with he DROID but i used 848 (w) and left blank (h) (anamorphic set to “none”), video bitrate was kept at 1500, which may seem low but looks great on screen. This helps to keep the file size down. I have compressed a 15gb 1080p mkv file down to a 1.8gb m4v/mp4 file. The DROID does not do well with files over 2gb.
