@olorin: This is caused by a change in rmeditor in Milestone 6, where it will not merge files with a different maxBitrate. Here is what you need to do to get around that, until AutoRV9 1.3 final comes out.

1) Find a copy of an older AutoRV9, or Producer Milestone 5.
2) find the old rmto3260.dll in producer's tools folder. In AutoRV9 this is in Softs\Rp9_Light\tools
3) Goto the same folder in the new AutoRV9.
4) replace its rmto3260.dll (6.0.11.434) with the old one (in my case v 6.0.11.433)

now you can merge the files you just encoded manually:

5) open cmd line window, cd to AutoRV9\softs\Rp9_Light
6) then type

rmeditor -i <main_file.rmvb> -i <credits_file.rmvb> -o <final.rmvb>

Also, since you just replaced rmto3260.dll, the next time you encode something like this, it will merge just fine.
