QT Animation+Alpha and Matte Key fun

After a three year hiatus to FCP I'm back on Avid. The transition back isn't nearly as bad ad going from Mac back to Windows. Anyway there are a few things I used to do in FCP that I can't figure out how to do in Avid and both have to do with Quicktime Animation Codec movies with embedded Alpha channels.

So, I have this Lw3rd provided by the client. It animates on but not off. So I want to take the first 10 frames reverse it and put it at the end to make an animate off. The problem is that when I double click with the Lift tool and apply "Reverse Motion" to both the fill and the matte layers the matte layer gives me the "Wrong Format" error and the key gets all messed up. Does anyone know how to do this in the Avid (MC 2.8.1)?

Also, in FCP I used to use the Travel Matte: Alpha transfer mode to "steal" the alpha channel from the Lw3rd and use it wipe the text on and off. It would be something like this: v1 video clip, v2 lw3rd QT+Alpha, v3 lw3rd QT+Alpha, v4 Text layer with Travel Matte: Alpha selected. How would I go about doing something like this in Avid (MC 2.8.1)?

Thanks in advance for all your help.
