Problems playing Mpegs o Quick Time

by alexnovo / June 18, 2005 11:53 AM PDT

Hey guys, I am an Mac Newbie- I switched from Windows XP and have had my iMac 2.0 Ghz (running tiger) for a week now. Most of the switch has gone seemlessly. I say most. I had a number of video files in MPEG format on my windows machine. In Windows the files ran fine in the Windows Media Player 10 or in Quicktime. I transferred the files to the iMac and about half are having problems. If I open them in Quicktime (Pro-version) Quicktime freezes and I must force quit. If I run them Windows Media Player 9 for Mac, i get a message that the file type is not recognized. If I run them in M Player OSX, I get full audio but no video. As other MPEG files that I transferred seemed to run okay, I thought that maybe the files had been corrupted in the transfer. So I deleated the files from the iMac and retransferred them. Still the same results. Other than knowing they are mpeg files, I have no idea if they are a particular type of mpeg file (nor do i know how to find out). If I get file info on the files I get he same type of information that I get on the files which run. Any suggestions?

The issue of coding or codecs.
by R. Proffitt Forum moderator / June 18, 2005 10:32 PM PDT shows the issue here. What CODEC was that MPEG encoded in?

Hint: Find a tool to examine the video file and report the CODEC.

Nice link, Bob! Thanks.
In regard to MPEG's, is the MPEG 2 codec for quicktime still a seperate product? I find that many MPEG's that give people trouble are either 1 or 2.

Just guessing.

My bet is yes. Here's why. The MPEG2 codec is one that would enable DVD playback PLUS a homage (money) is demanded by

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?
