scenery compatibility

[peteramd]

what I mean actually is if I need to install the previous AST Tech Photo-Real Brussels as well as Brussels HD. I don't think so. In fact I raise this question because sceneries takea lot of space and as new sceneries appear it may be useful to delete some of the old ones not needed any more. Currently I did a complete re-install and I did not install the AST scenery any more but just the Brussels HD and Belgium 2012 and it seems to b e quite OK
