Dear Cyberlink.
If you are reading any of this, please don't advance this "some can and some can't load and edit .flv files in PD issue", ahead of the other issues and requested features that have hopefully made their way to your "To Do" list.
In my humble opinion, you've got bigger fish to fry than .flv support.
Besides, give some thought and consideration to all those File Conversion Software vendors. They've got kids to feed too. Click here PDtoots for a collection of PowerDirector Tutorials and Tips
