I've found recently that if I capture without scene detection and if I set the rollover point to 4GB (I'm using W98SE still) then VV3 captures faithfully. But if I ask it to capture with Scene Detection on, at about the 1-hour point the system will lock up--and I mean REALLY lock up, to the extent that only a hard reset will bring the system back alive. What's going on? I note after rebooting that VV3 had detected anywhere from 100 to perhaps 140 scenes before crashing everything.
