I am looking into buying the Sim2 300 extra or Link. What I would like to know, is it worth upgrading the DVD32R with the PSM192 to enable the use of the DVI output (TAG's new IAG website states that this upgrade is still available). Are there any outstanding compatibility issues regarding the DVI output, using either DVD or SKY+, on PSM192 with Sim2 projectors? People mentioned problem's on TAG's own forum regarding this a while ago. At present we will be using the DVD32R, SKY+ and sometimes a PS2. I think I understand that the Sky+ could also be routed via the PSM192, DVI to the projector. If this was the case what benefits would there be in buying the Sim2 300 Link over the 300 extra?
