Permissions for System:

It;s not System's permissions that matter here but those of individual Users and Groups of Users. Look for diffs in these particularly those that are common with XP's Users.

XP has just as many settings available for each file; they are a property of NTFS called Access Control Lists (ACL). They are just hidden in XP Home until you take 1 of my solutions. There is also a CLI for doing the same called CACLS.

XRaySpeX,

Both files have Group or user names with 8 entries and the list is the same in both, however, interestingly, 4 of those items in each list are "?Account Unknown..." with only Read & execute and Read allowed.

Mp4 files on the Win7 E:\ storage drive have only 4 listed entries without the 4 "?Account Unknown..." items which are included in the lists pertaining to the mp4 files on the Win7 OS drive.

Perhaps that is relevant to the problem?

In a Command Window, CD to the folder containing the 2 files in turn, then issue the command:

CACLS "filename"

and post results.

It does work for individual files but if the name contains spaces you need to quote it in "s.

Make sure all other PCs are networked online at the time in case that is the Domain being looked for.

http://farm7.static.flickr.com/6141/6038333008_28379... this command worked on the file that I copied across the network yesterday but it did not work on the offending file that I was having problems before.

Not sure what is going on with this procedure?

No, that didn't work. You need to put the quotes round the whole of the file's pathname, as in:

CACLS "C:\Users\you\Videos\Redwing 13-01-10"

That's why I told you to CD 1st before doing CACLS, to avoid such problems.

Do this for both a file that was troublesome on XP and one that was not.

Which "both files"? From what you said earlier I thought you need to compare a file on Win7 C:\ that gave trouble on XP with one on Win7 E:\ that didn't give the trouble?

Yet here you go on to say that "both files" have the same 8 entries, yet files on E: have only 4 entries.

XRaySpeX,

Note I had to use ICACLS and add the file extensions for it to work - both are H.264 encoded videos.

This was to compare the permissions of video files on the Win7 C:\ and E:\ drives: i.e. files on the C:\ drive have 8 listed entries and files on the E:\ drive have only 4 listed entries, hope that is clear now

XRaySpeX,

http://farm7.static.flickr.com/6142/6039637465_62415... - used CACLS for both files but had to add the file extensions again and of course " " for "C:\...\Redwing 13-01-10.m2ts"

As in the previous test all networked PC's were online.
