I moved this thread to Q5/Q10 Pro because I presume that is the box you have if you're a new user.
How are you sharing the movies on your network (Samba/Windows share, NFS, uPnP/DLNA)?
Do you want to use Kodi?
Presuming that you do want to use Kodi (better media browsing interface) then this guide is a good start: http://kodi.wiki/view/Quick_start_guide
Section 2 onwards.
The simplest "Home group" option isn't working for me at all. The SMB option works partially, wheres the Q10 Pro is unable to find any computers on the network neighter with LAN->Seacch nor within KODI->SMB Source. So I had to add every simple shared folder data manually in KODI. Wery odd and unconfortable way. I've allready described the problem in a seperate thread, but -tho' many didn't report this failure- it seams i'm not alone with the issue...
Still calming myself, that's just some network setting related error on the Windows PC side, but I have done and tried dozen of settings variations, even with my firewall, but still can't find the solution... If any would have an idea that works to fix this, would be superb....
