help with media files SD Card

[bazza1974]

Hi im new to this site
I am trying to copy some movie files to my sd card and playing movies on the scroll excel
not having much luck so far, I have tried several different media files
currently have vlc, mx player and the default video player installed no luck
I have tried video converters .avi .mp4 .wmv no luck either

I also tried placing one of these movies straight onto the tablet memory and it works fine
please help if someone has come across this before

I only have the 4gb scroll so sticking the movie files on the tablet is not an option

many thanks Bazza
