I'm not sure if this would help your situation or not but try running it in compatability mode. Right click on the application and it brings up 3 tabs. General,shortcut,and Compatability. Click the option that works for you. It may just be that when you went to XP, the OS wouldn't accept the driver files for your video card which is why that happends. It also may be just a setting in the game. Try hitting Escape while playing it and go through the settings. Start with the bare minimum and work your way up. I dont know if any of this helps but you can give it a shot!
I have been having the same problem that all of you are with the choppy and skipping movies.
Current System Specs:
AMD Athlon TB 850
Asus KT-133 Mainboard
256 MB PC133 SDRAM
nVidia GeForce 2 MX-400 32 MB AGP
Gamesurround Fortissimo 2 PCI Audio
56x CD Rom max
30 GB 5200 Western Digital ATA100 HDD
I have been experiencing 2 difficulties with this game: choppy movies and the targeting reticles do not appear correctly. Through a twist of fate, when I upgraded from my aging K6-3 processor, the motherboard at the time was a FIC VA-503+, I had origionally gotten a Shuttle Spacewalker AK-10 and that is when the reticle problems started. After changing my SB 16 PCI card to the Fortissimo 2 because the 16 could not play MP3's properly, the MP3 audio was all crackly and totally unreadable, the MP3 problem was fixed but the movie skipping bug sat in. I then changed to a SY series motherboard (wish I could remember the exact make and model) and both problems disappeared. While the manufacturer was different, the board was almost identical to the Shuttle Spacewalker AK-10 in terms of specs and capabilities, but an EM surge toasted it through the internet on the second day and I replaced it with the Asus KT-133 and both problems set back in again. So my conclusion is that your problems can be fixed or are at least caused by a conflict by your motherboard's management of it's resources, the one we all agree on at the minimum is the sound cards. If anyone gets any more details on how to resolve these problems, I'd greatly appreciate it.
I'm not a expert but I think it's your OS. My understanding is XP is like NT.
Not very gamer friendly. Maybe someone with more experience can say for sure. I use Windows Me with basically the same system as you and didn't have no troubles running wing commander 3-4 & Prophecy.
I got it to run under W2000 AS. The movie skips a little. But it does play under win98 flawlessly. MS stated from the beginning that backward compartiblity was not their goal with W2000/XP. They really needed to leave 16 bit programs behind. This is a good thing.
Now don't get me wrong I am in the anti-MS camp. I think they should be broken up. But being a sys admin I understand the need for MS to move forward and some older games aand program need to go. This is why you'll need to have a DOS and Win98 machine. Right now I am dual booting Win98/W2000 AS and I have a DOS machine.
If you thing your having problem now wait till they releasing a 64 bit comsumer version OS. Games release before XP will most likely not work.
