These guys are an honest company. I paid and got my serial number very quickly. Also, tech support has been great. I've used email and chat. Chat is usually the better way to go if they are on and my experience has been that they usually are on. You can access them via chat or email from directly within the app.

They've always been very helpful and quick to fix any bugs tha we've found. I mean this in a very literal sense. There as always been an update anywhere between 1 to 4 days after reporting the bug.

Besides all of that I mainly use it for PAL to NTSC conversion. It works very well for this. It allows me to built simple menus too. It's really a great app.
