Mac Forum / Applications / Media Player / November 2004WMV files that used to play fine are now "invalid format"
I'm using WMP 9 on OS X. I have a number of WMV files I've downloaded that used to play correctly in WMP (I'm not streaming them; just opening them on my hard drive). Now when I try to play them, some work, and for others I get the "invalid file format" message. I've deleted the prefs and plist files; no difference. I've tried running these files, WHICH USED TO PLAY JUST FINE, in the exact same version of WMP, off a DVD I burned weeks ago, with the same "invalid file format" result, so I know they haven't been damaged. I did recently upgrade from OS X 10.3.5 to 10.3.6. I can't find anything online that reports this as a problem. I've tried these files in Mplayer and VLC. The ones that work now in WMP also work in there. The ones that don't play anymore in WMP also don't play in the other ones (I don't know if they worked there before--I'd never tried them in anything other than WMP.) Is this a codec issue? I haven't deleted any. Could the system upgrade have removed some? How do I get them back? Any ideas, please? Thanks. - Bob > I'm using WMP 9 on OS X.

Try deleting the pref and .plist file for WMP. It very often helps for these weirdnesses :-\ If you need more info on how to do that, it's is somewhere in the FAQ there: http://www.cortig.net/wordpress/index.php?p=8 (I really need to put that on a more official web site :-\ ). > I did recently upgrade from OS X 10.3.5 to 10.3.6.

How do I get them back? Nah, you can't really do anything to the codecs. I really suspect it's one of these issues with either the prefs or permissions on the drive.

Retirez NoSpam de mon adresse pour m'écrire / Remove NoSpam to e-mail me Thanks, but as I said in my original question, I've already tried deleting the prefs & plist files, and it had no effect. Also, applying Microsoft logic, I've deleted and re-installed WMP, and restarted my Mac a few times. No difference. Suddenly the majority of my WMV files have been rendered unplayable. I'd be willing to blame 10.3.6 somehow, except-- I have Virtual PC, and I tried playing the files there. Same behavior -- the ones that still worked, played fine in there. The ones that stopped being recognized as valid formats were also invalid formats in Virtual PC on the Windows platform. I also wondered if it was my external Firewire drive and a known problem with 10.3.6. But the files also don't play from a backup data DVD I made a few weeks ago, before I upgraded. Again, these are files that I succesfully played on this system before! I haven't found any rhyme or reason why some of my files play, and others are invalid -- some were from the same source. The modification dates on these files haven't changed, and they're still the same size. Is there any software for "fixing" corrupted WMV files??? - Bob > > I'm using WMP 9 on OS X.

THat's why I was thinking about the prefs. I was looking for something that might have gotten corrupted and crippled WMP. Did you also repair the Permissions on the drive ??? (this time I read back and saw no refernece to permissions ;-)) ). > I also wondered if it was my external Firewire drive and a known problem > with 10.3.6.

I really think something messed-up the player. > Again, these are files that I succesfully played on this system before!
