I bought a 4gb card and love it, the problem I am having though is that once I have transfered any video or music I am having an issue with it. The video plays fine for the first couple of seconds then the audio drops out. This has happened with a couple of video's so I know it isn't video specific. Both video's and audio play fine on my laptop, so the problem appears to be with the blackberry. Any suggestions is appreciated. I am using all stock software so if you have any software upgrade suggestions I am open to them also.

Oh and yes, they are in AVI format.

Thanks,
Dave
