Video FLV don't play

Hi, I'm from Brazil and my English is very bad. So, I'll write in Portuguese.

Um vídeo no formato .FLV não reproduz. Ao apertar "play" pelo Media Player Classic, ele aparece na barra de status "reproduzindo", aparece o tempo de duração do vídeo, mas não reproduz. Nem áudio, nem imagem aparece, aparecendo apenas o ícone do MPC. Eu tenho instalado a última versão do K-Lite Mega Pack 12.0.4. Uso o Windows 7 Ultimate 64bit. Já tentei instalar os novos codecs LAV Video Decoder 0.68.0.10-git. Já instalei diversos players de FLV, mas nenhum funciona. Também tentei converter em MP4, WMV, AVI e não converte. Ou dá erro, ou converte com tamanho de 0Kb.

Configurações do Computador:
Processador Phenom II x4 955 Black Edition 3.20Ghz
Memória 4 Gb DDR 3
VGA NVidea GeForce GTX 760.

Pelo MediaInfo v0.7.83 tenho as seguintes informações do meu vídeo:

Não é apenas essa mídia que dá problemas. Diversas outras mídias também dão problemas semelhantes. Mas não são todos os vídeos no formato .flv que dão problema.

Pelo Codec Tweak Tool 6.0.6 tenho as seguintes informações:

LAV Filters is included in the codec pack. You don't need to install it separately.

I suspect your FLV file is a bit damaged. That can happen if you start the download somewhere in the middle during playback. A little tip to get proper downloads is to refresh the page before you start the download. Then it will download the whole file and it should play correctly.

I use the Internet Download Manager (IDM) 6.25 Build 14 to download the videos. But just one website this happen. I don't know why.

Which website?

Report the problem to IDM. They may be able to fix it.

It download, but didn't play. What is the problem: codec or the video?

That link is not working anymore. Please copy the link of the webpage that contains the video, not the link of the video itself.

This is the link, but it needs a password.
