The latest version of atiumdag.dll will *not* work with the game--from Crimson 16.1. The game exits with an error message, but the RtK log file told me which file the game was having trouble with. However, I found an older version of the file, 7.14.10.911, and when placed in the game's root directory, the RTK runs fine, including all of the videos. (Need to set stretch=0 in the RTKKrondor.ini or you just get a black screen and sound.)

I set compatibility for WinXP svc pk 3; admin mode, and the game runs fine.

The game is running in its software mode, however--am still tinkering with the engine to see if I can get d3d working with the game. If successful will check back and report.
