Hi all...I have a Hewlett Packard Pavilion desktop PC with a Pioneer DVD player. Back in February, I brought it in for service because the DVD player would not work (error message: Another application is preventing DVD playback). The service tech easily found the problem and fixed it; he said he had to change a setting on the graphics card for the DVD player. It worked fine after that. I haven’t used the DVD in awhile, but now I find I get the very same message as before. That service center is now out of business and HP support is keeping me on hold for an eternity. So, my question: How do I change the graphics card setting? I can’t seem to find this anywhere. Thanks in advance. Jon
