In my experience GTR2 engine is able to correctly save (=extract) HOTLAP replays only for the last stint (the time between being in garage). That means if you make a good lap, visit garage and start another set of laps but with no luck, you have lost your hotlap replay for your good lap.
Of course the lap is visible in the FULL replay but picking it from there is something I haven't even bothered to try yet (I think it is possible). And somebody might consider that as a hacked lap.. ; ) which it basicly is because it is not an original, GTR2 created hotlap.

So after a successfull lap and visiting garage, don't start another stint, but exit the session and go save your hotlap replay (OR let a nifty program like VcrSaver
do that saving for you automatically, but you will still need to exit the session after garage time).
