[MacDV] Re: From the DV Expo this week in Los Angeles

(Rod, the link worked for me make sure the part after the "?" is  
included in the URL.)

This thing is basically a USB capture device that goes straight to MPEG  
(1 or 2), and it does not include the drive required to actually burn  
what you create.

I'm skeptical about a couple of things:

- cheap hardware MPEG encoders usually don't deliver much as far as  
quality is concerned, then again I haven't seen any output from this  
specific device...

- I realize that the USB interface can *theoretically* handle the max  
data rate that this thing can produce (8 Mbits/sec), but the spec for  
USB 1.x maxes out at 12Mbits/sec, which doesn't leave much headroom for  
any other devices on the USB chain.  Realize also that video capture is  
a "real-time" action, and the USB interface was not designed to handle  
such demanding "real-time" tasks.  It may require it's own dedicated  
USB port (no hubs, keyboards, etc.), in which case there is a chance  
that it would work fine, but that also means you need a Mac with two  
USB buses (not just two ports, but two separately controlled USB  
interfaces).

Having said all that, this product *does* seem tempting -- imagine  
being able to *easily* create an SVCD in *real-time* on your Mac...   
Real-time MPEG-2 encoding at 480x480, and authoring to (very)  
inexpensive CD-R media.  That is, if it works as advertised.  If anyone  
gives this thing a try, definitely let us listers know how well it  
works.
