Not sure what you're asking??? But, yes, the exporter doesn't move that fast. I have had problems with it since receiving our 844x. Even talk with Tech support and was told this was an issue they were working on. This is before the collapse of Media 844x.
We have 2 reasons to export files. One, we want to use it with our Media 100 HD, then we will export 'self-contained' files for the HD system. But most of the time, I'm creating DVD's, so I just need a 'by-reference' file to use for encoding. Exporting a 'self-contained' file that is going to be use to create another 'video file' is an unnessary step AND it's a double encoded/rendered file, which is never good.
