Preflight process or problem by viewing some mpg

[chevy]

Sometimes trying to view an mpg blcoks the Finder or uses a huge amount of CPU. I have seen that the Process involved is named preflight. How do I correct that ? Any way to update this process or prevent it to be started ?

If I use column view, it is started as soon as the mpg file is selected.

Any help available ?

Hmm...sorry I can't be more help here. I've seen a similar (perhaps identical) problem, but never came up with a solution. There are MPEGs that can be at once encoded by PCs and unreadable by Macs, and yet identified as a Mac-readable format. So the Finder/QT hangs trying to open them up, because it's convinced it's a readable file. I've never found a solution other than killing the process.

Try using MPEG Streamclip to "Fix timecode breaks" and then "Convert to MPEG" (the latter outputs the file within a new MPEG program stream file.)

And you might look here for more help...

Hmmm... I'd hope he'd have gotten his answer already, seeing as how this thread is 3 years old!
