I have been experiencing problems playing back windows video files\nafter my computer's operating system was rebuilt. I hope that someone\nwill be able to help me recover these videos as they represent many\nhours of work.\nI have a Firebird XE Professional and have recorded videos using the\nDViCO plug-in for Adobe Premiere, version 6.02, onto a Windows 2000\nbased system. This system has three hard drives. The C: drive contains\nonly the operating system. The D: and E: drives contain the video\nfiles that I captured using the Firebird XE Pro card. Each of the\nvideo files have a .avi component and the series of associated\ntemp*.dvv files with sizes up to 2GB.\nRecently, the Windows 2000 registry became corrupt and was\nreinstalled on the C: drive only. During this process, no video files\non the D: and E: drives were changed at all. Their drive partitions\nwere not changed, either. After the reinstallation, I have tried to\nplay back the video files using Window Media Player version 6.4. With\nsome files, only the audio is present, but there is no picture -\- only\na grey screen is visible. Some of the other files do not even open\nunder the media player. I have the same problems when I use DocuCap\nversion 2.30.\nI therefore have the following questions:\n1) Does a change in the operating system registry affect AVI files,\nor specifically, the files recorded using the DVICO Firebird XE Pro?\n2) If the files have been corrupted, can they be restored in some\nway?\n3) What codec must be installed in Windows 2000 to view the files\nproperly?\n\nThanks in advance.\n\nJeremy.
