Margro TVServerXBMC - Slow Jerky SD channels. HD is fine.

I am currently using margros build - xbmc-margro-20120730-a1cff1d-dx.exe

I have it set up to use my Mediaportal backend which is stored on my server on my network.

I currently have a few problems.


1. Firstly I am in the UK viewing UK tv. When viewing HD channels its fine. My TV runs at 50fps and the hd channels play at 50fps. Everything seems smooth and working well.
However when I view SD channels my tv runs at 50fps but the sd channels only play at 25fps. So everything seems a bit slow and jerky.

If I use mediaportal client and view sd channels they play at 50fps and are smooth and work fine.

So is it possible to play the SD channels at 50fps (like mediaportal) or not ?

I can see its only playing at 25fps by pressing the 'O' key on the keyboard and looking at the W (fps:25.24 CPU 4 core(s) average: 0.8%) . This says 50fps for hd content.


2. None of my TV Groups are coming over. I am just using the default settings and all I get is one big All Channels group. Any ideas ?


3. When I go to the TV Channels view , some of the channels don't have listed what programme is currently on and a description underneath on the right, however if you go to the epg view it shows there.
