Can't display video ( sounds only ) in some flv files

Dear sirs,

I've installed and updated to 10.6.6, but there was very strange that,
one of my flv video file is sounds only..., but it is all right in ver 8.x or 9.x...

You can download my sample file from

https://drive.google.com/file/d/0BzJF2SZgJ5GjQlAzYW1Od09ObGc/edit?usp=sharing

Please help me... thank you.

I have tried several old versions, but none of them show the video for this file.

Which filters are listed in "Play > Filters" in Media Player Classic for a version that works for you?

Dear adm,

sorry, it may be my wrong memory...

please help me in this condition, the old can play is my wrong memory...

and the file is download from:

http://www.twitch.tv/nanoha_suki/c/1266958

I was able to download a working video from that page. It has a size of 426 MB and a duration of 27:58.

Your downloaded video only has a duration of 17 minutes. So you probably did not start the download at the beginning of the video. That can sometimes result in an unplayable file. It depends on the website.

I used the "DownloadHelper" add-on for Firefox to download the video. The trick is to start the download when it has been playing from its beginning. If you have used the seekbar to jump to another position in the video, then you need to refresh the webpage before you start the download.

Dear adm,

Thank you for your help, it's ok now.
