Best Program to convert video without losing quallity

[Loplop]

I need to convert some videos over to a different format due to the fact that Nero Video says the audio is unsupported.
Looking for a program that can do it:
#1 with without quality loss (does not really need to be compressed)
#2 Failry quickly.

Any suggestions/

Anytime you convert a video file to another format it will lose some quality,i wouldn't trust nero for any statements.Do you need to use nero?

If it is only the audio that is unsupported you can use "avidemux". "Click direct stream copy" for the video and click whatever you want to change the audio to.
If you want to change both audio and video 2 good free programs are "VidCoder and HandBrake"

What format are the videos now?
What format or container do you want to convert to?

Do I have to use Nero? For now yes. It's the best program that I have to author blu rays at the moment.

Holy hell! Avidemux did exactly what I was hoping to do! Took your suggestion and left the video untouched and just changed the audio output and in less than 3 minutes, I had EXACTLY what I needed!
