If you have a look
here I have a photo of my home setup. If you look at the top right side you will see that I have an A4000D that I have the Video Toaster 4000 and Flyer system installed with CyberstormPPC. I have all my TBC's and Flyer drives installed in the Tower case just beside the A4000 I have 2 Cheetah 36gig and 4 9gig drives on the two SCSI video devices and one Barracudah 4.5gig drive for audio. I had to install 3 fans in the desktop and there are 6 fans in the Tower to keep things nice and cool.
The composit output of the Flyer is actualy very good at 480 lines D2 quality. You can get an add on card that will give you an S-video out that boost it to 525 lines. (remeber that DVD's are only 480 lines) so as long as your recording device is digital your getting a great poduct like me I record straight to my PC and make DVDs out of it.
