I downloaded a video and i moved it to my mobile but i can't play the vid please help me

some phones are too low speck for videos try charging it and shutting down the phone maybe the phone is to low spec to cope with the video you are playing.

that might be that your browser doesn't has a plugin for playing video on it,you need to install adobe flash player to play video on internet browser you can download it here

remember to restart your browser after installing flash player
please let me know if it's working or not and thanks for using fixya

If you can't play videos once you've successfully installed the YouTube for Mobile app, one of the following issues may be causing the problem:

• Your phone may not support streaming video. Check by trying to play a video at http://m.youtube.com
• Your streaming video access point may need to be configured outside of YouTube for Mobile. Depending on your phone and mobile data provider, this access point may need to be the same or different from YouTube's. For more help with these settings, please see the "Access Settings" article.
• If you've successfully played videos with YouTube for Mobile before, your network connection may not be strong enough at the moment. Please try again later.
• Your carrier might block RTSP traffic which is required to transfer the video.
  
  hope this helps

it means that the vids. that you're streaming is in a format that is not supported by your phone. you need a special streaming vid. application to properly stream videos,like real player online,mobile netflix or youtube for mobile.
hope this helps and gives you a hint. :D

where did you get the vids from. it sounds like the codec used for the vid is not ipod compatable. you may be able to convert them using free software like anyvideo converter or ipod robot. i tunes can play them because it has a greater library of video codecs (anything installed on the system... almost)
