Video errors

[Urion]

Hello all, been trying to work on an amv using Basilisk. The problem is that Im using videos from two different groups and raw unsubbed episodes also. The problem im getting is I can append two different data rates (frames per second I beleive) without errors, if I start using 3 it starts giving me errors. I tried encoding them all and changing the frame rates to all be the same. But it is still doing it, so it has to be something else. So its either the videos being evil or its my codecs im usind (kazaa lite codec mega pack).
