Thanks for the replies. But I think you misunderstand my situation a little. As my subject states it's more the import / editing part of MPEG-4 that's really missing.
I know MSP8 have some limited possibilities for export to MPEG-4. But even that solution is not satisfactory. You are only able to export to an AVI container with Microsoft MPEG-4 type 1 & 2 and with some external codec, maybe type 10 / AVC / H.264. With QuickTime you end up with a MOV container, although it gives you type 10. Another problem is that none of these exports give you a real 'native' MP4 file container. Yes I know you can do this by taking an AVI export through QuickTime Pro 7.0 manually and get a MP4 file container, type 10 and all. But it is not user friendly and efficient, which it should be. And the import / edit problem still remains.
What I was hoping for was having MPEG-4 support through the whole process: import / edit / export. I do not want any: convert MPEG-4 to this / then import this / process it / export this / convert to MPEG-4 with external program solution. Each step degrades the quality and does not make for a user friendly and efficient solution.
Look at it this way. If you were forced to import / edit / export MPEG-2 contents the way you need to do MPEG-4 contents in MSP8 today. Would you be happy? I want MPEG-4 support built into MSP8 the way MPEG-2 is.
I did bring up this problem in a support case to Ulead in connection with MSP7. Got the reply that the issue would be forwarded to relevant departments, and that it was a possibility for next major release (MSP8). Guess the feature got below the 'important enough' line
Enough of my frustrations. I do not really expect any instant solution to this. But I still wanted to make others aware of the problem, especially Ulead

It may not be a big issue now. But there will be more and more users asking for this soon. For me MPEG-4 type 10 / AVC / H.264 is the current and future storage medium for all my video, both when it comes to quality and size.
