1. Just tried and I have the same problem, however I don't use those buttons. 2 buttons on the wheel and 3 red buttons are all I use in GTL (and from those 3 reds, 2 are to say "sorry" and "thank you" :biggrin:)
2. Some weird issues you got

I guess you already have set you PLR correct, but just to be sure:
"Replays Dated="1" // Replays have date in filename"
Otherwise the replays got overwritten every time...
Only happened a few times that I got issues with the replays (and I've done lots of GTL races

)
