When I attempt to render a 6.5 minute piece to .dv, some of the assets on my timeline get re-arranged out of order! Specifically, I have segments that I will call asset_01.dv and asset_02.dv on track 02. Asset_01 appears ahead of asset_02 on the timeline. But when I render the entire thing to .dv, asset_02 comes out ahead of asset_01! This does not happen if I render to mpeg-2, for example.

I could not reproduce this using MLT 0.5.0 and Kdenlive 0.7.7. I know others have reported similar problems, and I do not know if there was indeed a bug that another developer fixed. I would be kind of suprised if so because you said the problem only occurs with DV output, which is very strange.
