Convert an flv format

[albfullsoft]

I downloaded some videos from streaming tvs and when i convert with ultra video converter some seconds are missing and everything
else is OK but when i convert with xilisoft video converter the video tempo is changed(it means that hasn't fixed fps) and when i set 25 fps in xilisoft settings the audio and video arent sync anymore. Do anyone have idea how to convert this video perfectly, no missing seconds and 25 fps.
P.s i tried many other softwares but they dont fixed problem.

We need more info than what you have provided...

Which is the format you want the FLVs to be converted to?

And why can't you watch just the FLVs themselves?

For the time being, I can already say that most veterans over here think Xilisoft and similar programs are rubbish

Funny, that's the thing that had immediately popped into mind. You're using terrible software.

What is the video format involved there? The .flv extension doesn't tell you that much. Open one of the files in mediainfo and post the results in text mode here.
