I used to have this error message always but I was able to solve it by either restarting my computer or just restarting the Media Center and sometimes I even used System Restore to a previous date as well to fix this issue. So, just recently, I was getting the error message that a recording has failed. I launched the program to find out why and then got this error message that files needed to display video are missing or corrupt. I followed all of the above but still nothing worked for me. I am able to play the previously recorded programs and also see the programming guide but the problem is the I am not able to record anything new and also cannot watch live TV or cannot even play the videos that are on the hard drive from other sources. I have got a HP Pavilion laptop that came with a external PVR. Any help would be appreciated.
