problems connecting to my le40b750

Hi all,

I have downloaded Serviio as I have heard many positive things about it... however, I have encountered some problems which I hope you can help me with...
I am able to use the TV internet and view some files on my laptop using the TV (smasung LE40b750), when I click source on the remote I have 2 options:

DLNA1 - SNUFKIN-HP:Guest:
DLNA2 - SNUFKIN-HP:Snufkin:
* I guess these refer to the accounts I have on the pc.

but I can't see all my movies (all are in MKV format) or the serviio server (shouldn't I c something like DLNA3 - Snufkin-HP:Serviio???)
within the serviio console I can see the following:

Green dot - IP Address:192.168.2.100 (which I know is my TV ip address), Name: Samsung DTV DMR, Profile: Samsung TV (B-series)
Orange dot - IP Address:192.168.2.101 (which I know is my laptop ip address), Name: Unrecognized device, Profile: Generic DLNA profile.

Please advise on how to continue
