Your problem is because you are trying to view ISO files. TViX claims ISO compatibility but after trying to go the DVD ISO route I soon discovered that viewing ISO files is a joke. Some ISO files will work with stutter, others wont work at all. Use winrar to convert those ISO's back to folders and your player wont have any trouble with them.
I have still yet to find a way to make this stuppid &$%*!@# tvix box access a vista share using SAMBA. I can get it to work using netshare 1.09 but its rare I can even make it threw a movie without netshare losing connection to the TViX box then having to reboot the Vista PC before I can gain access again.
glesgaguy...... although I think you are right, it really doesn't solve my problem. Going back to XP is not an option for me because my partition I am using to store all my media is larger then 2TB(XP can only have partitions 2TB or smaller). There has GOT to be a way to trick these dam boxes into accessing Vista using SAMBA. The NFS is a nice thought but still buggy as hell and not to mention Netshare only lets one TViX box at a time access(I have three).
Now. I think I will go find an old computer or some video equipment I'm not currently using that I can take outside and smash to pieces to release a little anger.
