My coby mp600-2g does not play video.
I had the same problem with playback of video with coby mp60-2g, and it took a couple of weeks to figure out. I wasted a lot of time installing video file converters, and trying to convert my wmv files to MTV,.... it wasn't necessary!
The Coby Media Manager software that comes with the device actually works for converting wmv files (for example) to mtv files. It's just a little confusing HOW IT WORKS. Unfortunately the 'Coby Media Manager User Guide' is very little help.
The key really is 'Synchronizing' your video to your player! But there's a little organizing of your files to do before-hand, which makes it easier when your ready to playback on your device.
For me it was easier to separate my audio files from my movie files in the 'Device' tab of the Coby Media Manger. This was the 'F:' of the Device content (middle third of the manager window) for me. I put the videos in the MOVIE.DIR folder. But you can't synchronize the video here. You must click on the 'Movies' tab on the left side of the manager window.
Under Movies, go to Library,... (now it gets a little confusing),.... immediately under 'Library', there is a 'Folder',....but that only shows what you have selected by clicking on the 'Video Folder', a little further down and slightly to the right.
So you must make your selection ('Import' video files and folders) by clicking on the 'Video Folder'! When you click on this Video Folder, you'll open a selection box, which offers
-Documents
-Music
-Pictures
-Videos
-C:\
-F:\
If you select only 'Videos', it will automatically select 'C:\', also.Which will import ALL of your videos on your C:\
If you select only 'F:\', it will only import the videos which you have put (as I suggested earlier) in the 'MOVIE.DIR' folder at the 'Device' tab.
NOW TO SYNCHRONIZE,....! (make sure you mp3 is connected to your computer).
You might notice, that if the device (mp600) already contains the file, then there will be a small icon which looks like the mp3, next to the file under the 'status' column.
BUT that doesn't mean that the mp3 will actually 'play' the video. It must ALSO be 'Synchronized', :o).
Once you've made it this far, Synchronizing is easy. Let's assume that you decided to Import all of the videos in C:\, and F:\ when you clicked on the 'Video Folder'.
Now if you go back up to 'Folders', and click on it ALL of your video files will be dislpayed. And the files which are already on your device will have the mp3 icon next to them. Also, when you clicked on 'Folders', additional sub- folders were displayed under the Folders icon.
The easy way to 'Synchronize', is to select the F: folder, with a 'right click',... which gives you the synchronize option,... clicking 'Synchronize' will synchronize-convert-copy all of the video files in the folder! Now, if you go back to the 'Device' tab and look at the video files, you'll see they have all been to converted to mtv files!
Now when you open your mp600, and arrow to 'Movies', you'll be able to play your videos!!
