Certainly. The nvidia-bug-report should show that 0/SyncToVBlank is set to 1. I've also tried it at 0. Also 0/XVideoTextureSyncToVBlank set to 0 and 1. I created a matrix for SyncToVBlank, XVideoTextureSyncToVBlank, AllowFlipping, and XVideoBlitterSyncToVBlank and tried every combination with no success. (I used those four settings because those four seem to be thrown around a lot in discussions on various mailing lists and forums I belong to)
