Longcat: I posted this in the comments thread for the Overseer news item, but I guess nobody reads that anymore, so here we go:
Hi. I apologize for falling of the grid completely, but I have three jobs and a lot of other stuff taking up my time:P
But to the point, I have finally managed to make the dvd version run pretty flawlessly and made a new updated dvd from my work. Midi is still not fixed though, and I had to discard the no cd patch available online as it made the dvd version crash. However, I can play it by mounting the dvd image in daemon tools and I must say it works pretty darn well:)
Basically what I've done is:
-convert all the video files to mpeg1
-update the game to v1.04
-set the processor affinity for Overseer.exe to run on a single cpu.
-twiddled with the settings in the configuration files somewhat
-the only thing you have to install now is RTX audio, the DVD Express Player is no longer needed, but you still have to configure the game to use it as none of the other decoder options function correctly.
Also note that I have actually improved video quality by deinterlacing the video and applying various filters. I'm pretty happy with it:)
Basically, all gog would have to do to make this work is to make their own working no cd patch for the dvd version. So gog team, please contact me if you need any assistance. I know there is interest in the community for this, but your lack of interest in our progress so far has been somewhat disconcerting:P
I made my modified version from the original dvd and am running the game on a new iMac with Windows XP through BootCamp for those interested:)

Longcat: thanks:) I would have never thought of using mpeg1 if it wasn't for you though, so kudos;)

Longcat: I'm currently playtesting and so far the only problem I have encountered is the old bug in the Anasazi ruins, which can be kind of a bitch to get by, but I managed it. I haven't seen that bug reported on here however, it would be interesting to hear if any of you who bought the gog version have experienced this? Or has the gog team found some miraculous way to solve it?

rjspring: So from this do I assume that the Overseer version offered on GOG is the CD-ROM version and no the DVD version?

Red_Avatar: Yes and it's not surprising. I bought Overseer shortly after release because I already had a DVD drive and the game came with both DVD and CD version (the DVD version having MPEG2 video which is of a lot better quality). Even back then it was a massive headache to get it working because the software included didn't do the job. The game was designed back when the DVD players contained the MPEG2 decoder instead of the software. I recall you even had to pick a DVD brand from a list to get it to work and it still didn't because my DVD player wasn't on there and needed software.
With some luck I managed to get it going but it was pretty buggy with glitches left and right and it was very crash prone. Too bad since the quality was a lot better.

Longcat: Hello.
I'm afraid I can't make the game publicly available as that would constitute software piracy.
The process is doable, but timeconsuming(in regards to converting the video files) and requires an intermediate level of technical know how. In other words, you don't have to be a programmer or computer wiz, but it would be useful to know your way around an operating system and how it works technically.
I have recently switched to windows 7 and haven't gotten a chance to try out the DVD version on it yet. I might give it a go later this week and try to write a more detailed how-to and post it here.
I'm sorry that I can't be of more help at the moment, I had hoped that GOG would release the unstable dvd version at least as an alternate download, but it seems we have no such luck. Either way, the most important tasks you can get started on is converting all the video vob files to mpeg1 and figure out how to use imagecfg.exe to set the processor affinity to 1.

Good luck.
