I recently purchase videowave 4.0..I own Sony TRV20 digital camcorder. It's proved to be a waste of money. The software does not support this camcorder. It will not recognize the existent of the camcorder. I have a gateway computer with recommended firewire card said to to 100 % compatible with the software. I spent [a lot] in order to have the ability to edit my video on computer. It is proven to be a complete waste thus far. I spent countless of time on mgisoft website in no avail. The company should anticipate this problem and should provide an update downloadable patch. Attempted to contact mgi by phone in no avail(spend may be..just wait for the darn human to respond). I hope mgisoft read this message. It's the only way that I might have a chance of getting messages to them.
