My question is only indirectly related to videos:
Over the last few days I have experienced someting strange when I downloaded videos from a website (http-download) using reget download manager (all in one piece and a steady download rate of 60kB/sec...no resumed broken dls!):
About 40 8MB-mpg-videos were corrupt (out of 300. 15 consecutive vids and the odd others. Most programs crashed when I tried to open the files with them except wmp. When I downloaded them again a few minutes later into a different folder they worked fine. They had exactly the same filesize and timestamp, CRC is different (sure it is).
Years ago I have experienced this with jpeg-files.
Does anyone have an explaination for that, is it possible to fix the corrupt downloads with a hex-editor (I have no experience in that at all).
regards

P.S.

actually I have found out why the files are corrupted:
In a first run I tried to download the files providing a wrong password, so I got some other 16KB-datachunk named like the real movie files. In the second run reget tried to resume broken download with the data chunks and somehow did not delete the garbage first. So now I am stuck with several hundred MB of unusable files.
Still one question remains: Can they be fixed with a hex editor?
propably...but can someone explain it to me?
