Serviio issues

Hi

I just started using Serviio - running the server on my Macbook (OSX 10.7.5) and rendering on my Samsung Galaxy S2 and Asus TF101 using ServiioGo.

Connected easily enough and so far streaming nicely both audio and video.

A few problems though:

1) Some videos appear in Serviio Go with the wrong titles. I changed the metadata settings to Use original title but then the videos disappeared completely and showed "No Content" in Serviio Go

2) mp3s appear several times in the audio folders, so an album will show each track about 13 times, making it over 100 tracks in total!

3) I can't view any image files - it just shows "No content" in ServiioGo

Any help would be gratefully received. Sorry if these questions are answered elsewhere in the forum - after searching I couldnt find any answers.

Thanks
L
