Problem with all video files

by GerhardL / October 27, 2012 6:19 AM PDT

Hi there,

I thought this might be common new bug but can't find any info on it.

I have a new MBP which I bought a few months ago. About 2 or 3 weeks ago I started having trouble with all my video files.

I can't think of the proper word for it (I'm not English), but it is like when videos online are lagging. It just freezes for 2 or 3 seconds, sometimes longer, and then plays on.

This happens on ALL my video files, regardless of the file type (I play MP4's and avi's mostly) or the player (VLC, QT or iTunes).

Please help - I can't think of anything I did/upgraded/downloaded that could have caused this.

Thanks in advance,

Why is a bug suspected?
by R. Proffitt Forum moderator / October 27, 2012 6:33 AM PDT

Was the user on Torrents or cracked software? Usually that's what I discover but the good new with Apples is we can reinstall the OS and save the files.

You did not reveal which OS so I'll lead with Apple's word about this.

Will try reinstall OS

Hi Bob,

Sorry, it's my first post here.

I'm on Mountain Lion (and have been since I got the laptop). Most of the files are from torrents yes, but not all of them - I also tried some music videos on iTunes that I got from the original CD's, and the other iTunes videos are downloaded from

Do you still recommend a reinstall? If so, I'll it tomorrow after I finish some work,a nd I'll report back.

The reinstall won't cause me to lose anything right?

The moderators will repeat this forever it seems. While Apple's OS reinstall has been very good only the folk new to computers would run with scissors or no backup.

I only have the clues given in your post. It could be simple maintenance issues such as a machine that has clogged cooling vents but I didn't note that since it's so new.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
