This clip seems a little demented to me, but here goes.
OK, I'm using HJSplit for this one, so you know the deal.
But just in case some of you don't:
1) Download both Zip files to the same directory (or to your Desktop).
2) Unzip/Extract all of the contents to the same location as the Zip files.
3) The second zip file contains the utility called HjSplit.exe. Open this utility and click the Join button.
4) Next, click on the Input File button and find the *.001 (In this case, its CementGarden.wmv.001). Open this file and click Start. Click OK when it says "Joining Completed".
5) Click Close then Exit.
6) View file as normal.
First one...
