about the video box popping up, open up the gp4 file in gp4builder, find the two objects as shown in picture
Change the marked sections to what is shown.
Also dont know if its a nvidia problem like gildoorf was having but some fences are showing in front or behind certain objects.
Fixing this is simple enough.
These tex files need to be changed to DXT1, opaque :
silverstone2001_Club_Hill_Gravel.tex
silverstone2001_page_026.tex
silverstone2001_page_26_red.tex
silverstone2001_page_026_NoGrass.tex
silverstone2001_page_26_red_NoGrass.tex
silverstone2001_page_178.tex
And these ones need to be changed to DTX1, Semi Transaprency:
