I have recently become unable to view and listen to wav and wmv files. I have all the latest updates to Quicktime but, while Quicktime launches, it doesn't play the files. Are there some settings I don't know about? If it became corrupted, wouldn't the updates have fixed that? I can look at Youtube videos, just not the wav and wmv files people send me.

On a possibly related note, it seems that the videos I view on Youtube are jerky - Like my computer can't keep up with the data stream, and skips frames in order to keep up with the sound. I hope I'm making sense. Is the problem with memory (or lack thereof)? I have a bad block, which has been worked around (I did a reinstall). Could that be the cause?

Thanks in advance.

    No.

    Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.

    You might have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them. Disk Utility's Disk Repair is not perfect and may not find or repair all directory issues. A stronger utility may be required to finish the job. If you have DiskWarrior that would be better at repairs.

    After that Repair Permissions.

    No need to report Permissions errors....we all get them.

    They are on my Mac that runs Tiger also. The later Intel Macs with Leopard or Snow Leopard handle them better.

    The more RAM the better, but it may not help with this issue. How much do you have?

    I have a bad block, which has been worked around (I did a reinstall).

    A regular reinstall will not map out bad blocks. An Erase and Install with a Zero out is the way to accomplish that.

    wmv files: you need to download and install Flip4Mac WMV Player from http://www.telestream.net/flip4mac-wmv/overview.htm (Windows Media Player for the Mac is no longer supported, even by Microsoft).

    YouTube Flash: yes, very likely your oldish Mac is no longer up to it, but:

    The latest version of Adobe FlashPlayer can be obtained from here:

    http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash

    (You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS.

    You should first uninstall any previous version of Flash Player, using the uninstaller from here (make sure you use the correct one!):

    http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157

    and also that you follow the instructions closely, such as closing ALL applications first before installing. You must also carry out a permission repair after installing anything from Adobe.

    NOTE: On December 8, 2009 Adobe announced plans to drop Flash Player security support next year for Mac owners whose machines run PowerPC G3 processors.
    "Adobe will be discontinuing support of PowerPC-based G3 computers and will no longer provide security updates after the Flash Player 10.1 release," said Adobe in the same advisory that spelled out the seven patches. "This unavailability is due to performance enhancements that cannot be supported on the older PowerPC architecture."

    Dear Dale,

    I did the Safe Install Disc Utility scan. All it said was "The privileges and permissions have been repaired..." No mention of problems. I don't have Disc Warrior, but I have Tech Tools. I ran the advanced suite of tests, and it reported no problems. I DO have all the latest updates for Quicktime, and all the other programs that play wmvs and wavs.

    Recently, I had the unit in the shop, which did a complete reinstall with the Zero out option.

    And finally, I have 768 MB RAM on the computer.

    Does any of this make sense?

    Thanks in advance,
    Fred J.

    Does it work any better now?

    Just to clarify, is one of your programs Flip4Mac?

    Hi Dale,

    So far, so good. I haven't had any unopened wav files. Thanks a bunch!
