user22711: A four Gig .MOV video file plays perfectly on VLC, Windows Media Player and PotPlayer but when imported into Adobe Premiere Pro 5.5 the following error message appears : 
"The file has no audio or video streams".
I've tried four different video file converter / repair tools (including Remo, Stellar Phoenix and StreamClip). All three tools actually worsened the problem instead of fixing it. Most of them made the file unplayable (as well as not editable). As a precaution, I only tried the repair tools on a backup of the file so as not to ruin the original.
I've searched but cannot find an example of a video file that plays back perfectly but cannot be imported into Premiere.

user23984: I had this same issue. I found 2 different solutions for my file.
The issue has to do with some kind of codec issue with newer versions of Adobe that no longer support certain .mov encoding types (or something like that)
Solution 1: Rename the file extension to .mp4
Believe it or not, this is actually working for some people. Read toward the end of this thread.
I tried it myself and was finally able to open the file in Adobe CS5. However, only the audio appeared in the timeline. No video.
Solution 2: Re-encode using VLC
There's a fix in this thread from Sasha L. (dated April 11, 2018) that involves re-encoding the file using VLC. I tried this and it worked. The steps once opening VLC are:

Click "Media" in the menu bar
Select "Convert/Save"
Choose your source file
Select your destination file type (click the toggle icon in order to access more advanced encoding settings)
Choose your destination file name
Export

When I used this method I was able to export a visual-only video (no audio).
Between the 2 methods I was able to export audio and visual and import them into Adobe Premiere so that they could be combined.
Best of luck!
