I always save a replay if I get a PB online as I heard it won't register otherwise, although somebody did say that's an old wives tale.
Yes, that is an old wives tale! Also until the recent 67 patch you couldn't just use the player.ini for any addon tracks for the 67's. The player.ini only kept the original papy tracks. Now the patched 67 keeps PB's for all tracks. A word of warning though, if you ever run the base exe (i.e. gpl.exe) it wipes all the addon times from the player.ini. I've reverted to using GPLRA for the 67's for that reason.
