Video file problem!! Please help!!!

[Sportsignings]

Hi everyone, new to this forum and really hoping someone can offer some advice....
I have a soccer autograph business in England & mess about with differant videos on my website.
Over a period of time have changed the formats of some of them so that I can edit them in Sony vegas.
I have 3-4 folders now (one unfortunatelybeing My Documents) which have video files
which dont seem to get on with my PC. When I click on them to open them the PC shuts
down for 4-5 seconds and then returns to the desk top......?!?!?!?!?! Example below

I havent saved the last 6 months worth of my website and getting a little switchy now as
I cant get into "My Documents" to grab the "diectory" folder. I can access jpeg files through a
paint package but as soon as I open it up it shuts down.

Heres hoping....Nick

PS: Tried opening in safe mode and still shuts down, maybe it isnt video file related but the
folders that crash out are all folders which contain recently edited video files.

Try disable the windows file thumbnail preview as it may cause the crash,

To disable, from Windows Start->Run type
regsvr32 /u shmedia.dll

To re-enable use the following command:
regsvr32 shmedia.dll

Thats great, is that safe to do??

[Baldrick]

Yes. And you can easily reenable it.

Oh my word its worked!!! Thank you so so much, that has plagued me for months

What has happening: a bad file or bad decoder was causing Windows Explorer to crash when it was building thumbnails of the vidoes (Explorer sometimes automatically restarts after it crashes). If you can figure out which file or which decoder was causing the problem you can remove/replace it and re-enable thumbnails.

ahhhhhh, I get it. Once again many thanks Im delighted.

Some decoders I know of that can do this: Panasonic DV Codec, old versions of the PicVideo MJPEG codec.
