I do also work from a 24" 1920x1200 (Sammy, innit?), but I have 4 locations/boxes from which I can either record, view or make backups... It is not that bad, the 1280x1024 resolution. Yep, native might be higher and really better, but it is still viewable.
No, this is not good for a permanent solution, but you could either view on another box, or add a monitor to your computer that supports 1280x1024 (keep in mind that DViewCam starts up on your 'main' monitor only).
We might have to wait for the really, really nice guys at D-Link to bring out a minor update release to fix the 4-5 bigger issues we've seen in V3.0 (resolution, multi-cam local/remote playback, multi-cam remote view, date/time selection, event handling and probably 1-2 more).
