Unable to resume download of videos

For context see this thread  http://channel9.msdn.com/posts/Anders-Hejlsberg-Questions-and-Answers

Basic jist of the problem is a trace like this from Free Download Manager 

----------------

GET /ch9/b0be/c77d5232-4d38-474d-80a5-9ed20166b0be/AnHourWithAndersHejlsberg_2MB_ch9.wmv HTTP/1.1

Server does not support download resuming. Don't stop this download; otherwise you'll have to start it from the beginning.

Strange thing is it's not all video,  for example, this one resumes for me

http://media.ch9.ms/ch9/b0be/c77d5232-4d38-474d-80a5-9ed20166b0be/AnHourWithAndersHejlsberg_high_ch9.mp4

but this one fails for me

http://media.ch9.ms/ch9/0ee8/30fd8210-58f1-4d61-a006-9ed200a40ee8/Devdays001_2MB_ch9.wmv

Also the trace taken above was supplied by user m4h4r4, but that video resumes for me.

Cheers,

Thanks for moving it here, Stephen. I hope this will get resolved.

@Duncanma: Seems to have fixed it for me, thanks!

@Duncanma: Yup, it seems this has been fixed. Another good news I notice is that it supports back multi-section download like C9 in the old days. It helps me accelerating the download process. Thanks, @Duncanma!

It was not working for me today and after some search I found this post http://channel9.msdn.com/Forums/Feedback/mediach9ms-VS-filesch9ms/a375ea718ff04a6b93d59ecc016eb27a

I modified all  'media.ch9' url to 'files.ch9' and bingo! It is working (though it still saysin log that server doesn't supports resuming).
