ResprungSetup for dual DV output?

I hope you can answer this --

I'm looking to buy a solution for a very specific business video application:

- Simultaneous recording of 2 DV streams: video and audio.
- Simultaneous realtime display of both streams: Video AND audio.
- Preferably both streams side by side on 1 wide display. 2 separate displays acceptable).

I'm looking to the likes of Pinnacle and Matrox on a PC platform (that should give you an idea of the price range)... :-)

I'm not familiar with Pinnacle nor Matrox, but Canopus has DV Capture which permits capturing 3 simul DV streams (your harddisk sub-system permitting).

For this, you need the Canopus DVStorm2 capture card for one of the streams. (However, DVStorm2 is now officially obsolete, but Ebay might have it, or the 'Marketplace' section at the Canopus Forums. Its replacement is the Edius NX for HDV. The DV Capture Utility comes with the package, otherwise downloadable from Support.)

The 2nd and 3rd streams are from an IEEE 1394 OHCI card in your system with multiple firewire connections. I haven't tried it with built-in IEEE 1394 OHCI. Only tried it with a PCI OHCI card and my DVStorm2.

For simul playback, a reasonably good graphics card (eg. the ATI Radeon 9600XT or equiv.) with dual head should be able to playback using software overlay two instances of Windows Media Player or equiv., one on each monitor without much problems. BUT...your audio will be mixed unless you can assign audio from one player to one sound card's output, and audio from the second player to a second audio card's output within the same PC.

That's going to be difficult without specialist software such as Wings Platinum Module Version which, apart from a whole host of other things, allows you to so assign, both your audio and video outputs, simultaneously, especially when used with other PCs configured as Slaves of the Master PC.

A possible alternative is a hardware playback solution using the SC Video Player (Dual Player version) also from Stumpfl.
