Ok,
After much struggling with all the different options I found that renaming the AVI folder seems to work. The thing is that I never had this problem with EU nor EU2.
I have found that if I install HOI fresh I can play the intro video and play at different resolutions immediately after installation. However once I turn off my computer and turn it on again say a day later HOI does not seem to remember that it was able to play the intro video and play at resolutions higher than 800X600 before and I can only play at 800X600. HOI installs OK and plays OK immediately after installation but after the computer is turned off and turned on again HOI "forgets" the graphic setting or something like that and no longer works at higher resolutions.
The bottom line is that renaming the AVI folder is the only viable long term solution. HOI now has no problems with resolution and I now save time by skipping the intro video entirely!!!
Thank you all for all your help.
