Ok, someone please give me some instructions.
I am using BB video converter.
I use Alpha dog.avi and converted it to the highest res.320*240.
I saved it first to my computer then copied it to my phone.
I am getting an error when the movie starts to play.
"Error playing - An error has occurred attempting to play media"
Any suggestions please.

Have you upgraded to the latest Blackberry Desktop Manager? SP2? It comes with Roxio to manage your media. When I drag and drop video it is automatically converted to the right type and resolution for my device. When I drag music, it automatically converts it to the right bit rate, and when I do pics, they are automatically resized as well. All of the behavior can be changed though, you can adjust quality, sizes, or whether or not they are even converted. Nice and easy.

Right on bro, i'm going to get it now.
I did however get it working but it takes quite some time.
I'll upgrade no matter what. Thanks again

Get the desktop working? Or get your video converted? At any rate the roxio thing is perfect. It automatically does it for you. And ... Your welcome!
