Yes. 3.1 will be released in the next couple of months. It will address the DV issue, as well as the alpha channel in AVI issue. Plus fix a couple of other problems such as AE 7 clipboard data support.
If there is a bug in the Windows version of pI3, please email wt support and let me know about it! EVen if it's been discussed on this forum before, or you're sure I know about it, please send it. I'll post a known bug list sometime soon too.
