weird overlay problem

I'm having a problem with video overlay. Whenever I try to play something with PowerDVD or DScaler (tv viewing with a WinTV card) all I see is a black screen. Upon further investigation I found that the video is playing behind the application. In PowerDVD I can see two small strips of the video at the left and right, and on DScaler I can see the picture for a second after closing the program.

Both of these programs work fine in the Administrator account but not in my Power User account. I'm using WinXP Pro, ATI Radeon 9500 Pro (latest drivers), and a Hauppauge WinTV-PVR. Is there some setting that's messed up or something?

Thanks for any help

One more thing. DScaler was working for a minute but then I moved the window and the above problem re-emerged and it hasn't worked since.

if it works under the admin and not under the power user , its a permission issue.

The best way is to contact the manufacturer of the pogram to help you with this problem.

in the meantime you can try the following.
1: reapply the permissions on the program folder and give everyone full access to the folder and subfolders and files.

2: go to start , run , regedt32, and look for hkey local machine, software and look for the power dvd (or the name of the program) and gice everyone full access to the registry key a,d sub keys.

3: make the power user temporary a administrator, reinstall the application under his account, make him power user again, and check if it will run now.

Success

Thanks for the suggestions but they didn't work. I checked the folder permissions and I already had full control for them. Same for the registry keys except that DScaler doesn't even use the registry. I then gave my account Administrator rights, made a clean install of both programs, and tried running the programs. They still just showed the black screen with video behind it.

Other than the initial OS installation you probably haven't used the Administrator account that much which is the right choice. I would go through all the WinTV-PVR settings in the administrator's account and see if there's any differences. Also you may need to perform the channel scans and all that again for each user.

Make a copy of the administrator account to use for troubleshooting.

To make a copy of the administrator's account

Create a new user. Log on as a user other than the administrator or the user whose profile you are copying files to.
In Windows Explorer, click Tools, click Folder Options, click the View tab, click Show hidden files and folders, click to clear the Hide protected operating system files check box, and then click OK.
Locate the C:\Documents and Settings\Administrator folder,
Press and hold down the CTRL key while you click each file and subfolder in this folder, except the following files:
Ntuser.dat
Ntuser.dat.log
Ntuser.ini
Select copy from the Edit menu.
Change to the folder for the new user and paste the copied folders and files there.
Log off the computer, and then log on as the new user.

See if it works like that.

Like i said before, contact the manufacturers.
This is a programmer error and not a windows error.
They should have taken care of that in the registry the program would install in the hkey local machine with full permissions and also in the folder and if the program install files in additional windows folder that all of those would have had the proper permissions etc. It's more or less the guidelines when programming a program that is w2k and higher compatible.

you can try to use the sysdiff.exe program of Microsoft to help you (or a similar program) this program will give you a snapshot of the changes made during a installation of a program.
when you know the changes you can do it for the other users then too.
see the following link.

btw sysdiff is in the resource kit of w2k.

I'm gonna try out the suggestions when I have time between my classes today, but I just wanted to mention that I recently made a clean install of everything in my computer just to clean things up. Before this both programs were running fine.

by estvb

Here's what happened. I was going to try a program called WinInstall LE 2003 to see what changes where being made during the program installs. I thought I'd take another shot at simply reinstalling the programs. Before doing this I added my regular account to the Users group (previously it was only a Power User). I installed them and they worked. I removed myself from the Users group (just to check) and they still work.

I don't know if the above group thing had anything to do with it working now or if it was some coincidence but everything's working now. Thanks for the help.
