TrendNet Camera saves ASF files.... They play badly.

I have a customer who invested in 4 TrendNet IP cameras that save to a Network Attached Storage device.
They only save in ASF file format.

Whenever I try to view any of these files, they are somewhat garbled and do not appear to play until 30 seconds in.  Suddenly then time index overlay on the screen will move very fast for 10 seconds, and then resume normal video.  I have tried using multiple viewer applications including VideoLAN and Windows Media Player.

When I view the live video from the web interface, it is flawless.  

My question is am I using the right player?  What else should I be checking?  Are these just sucky cameras?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

According to Microsoft
ASF files are containers for the streaming media, and normally Windows Media Video or Windows Media Audio files are found within them. This format has been superseded by WMV.
An .asf file may contain video and audio, and can also contain metadata in the same way that MP3 files do.
You can convert them to mp4 using vlc.
Open Vlc then top left open media then convert /save
ADD your file drag and drop
then expand the convert/save and choose mp4 with mp3 or WMV etc
click on convert choose your directory give it a new name save done!!
If you quickly look at the main interface VLC you'll see streaming in the progress bar as it converts.

I concur with advice given by Merete, although VLC player has most codecs,  I also suggest you try installing a codec pack.

K-Lite Codec Pack Mega, may be over-kill, but try it, as you can always delete it and use another K-Lite Codec Pack.
