The CS4 media encoder sucks big time. The integrated CS3 media encoder was much better. I'm also having troubles with CS4 encoding. I'm getting back to CS3.
If people have these problems, usually it is caused by:
1. Incorrect system or lacking setup
2. Heavy pollution and / or corruption
3. Operator error
1 is solved easily, 2 requires a reformat/reinstallation and 3 is very difficult to correct.
To which category do you belong? 2 or 3?
Sorry. Wrong topic. Misunderstanding.
