Quite a lot of Linux applications will have trouble accessing data over a network where the path begins smb://
The smb:// path is something fairly new and not all linux distributions/desktops follow that convention.
The best way round the problem is to explicitly mount your remote filesystem in the local one.
If you issue the following command as root:
mount -t cifs //JXP/Shared/Files/Video /mnt -o username=<yoursambausername>
after being prompted for you samba user password.
you will find that you can access the contents of your JXP/Shared/Files/Video directory directly under /mnt on the local machine.
The applications will be happy to access the information there.
You may have to substitute the JXP designation with the ip address of the remote machine depending on how your machine is set up.
You can vary the location your remote share is mounted to suit. I specified /mnt as most distributions have that directory but you can use anothe or create one for yourself.
