We are also considering to buy the LVR 6000. It accepts several different
kinds of input signals, PAL/NTSC being one of them but not the best. Instead
of Video Creator we will buy VideoFramer (VF). It enables you to output images
in different formats (D1, D2, Betacam, RGB, PAL/NTSC) all of them with
very good quality (broadcast) except for the PAL/NTSC. BTW, VF lets you
also digitize imagens from any source. VF uses one VME slot in your Iris
and it has also a V-LAN output. Because the LVR 6000 has a RS-232 input
we will not use V-Lan. So our configuration will be much simpler:

iris + VF ----> LVR 6000
 |         rgb   ^
 +---------------^
           rs-232

The rgb outputs in the VF are very good quality, you can easily control
the LVR using the rs-232, if you know the ASCII codes which Sony
provides in a separate manual, the LDM-5000 Interface Manual.
If you want I will be glad to discuss this further via email.
