Yes, compressing NBTV wave files is an interesting problem, because you have video on one channel and audio on the other, both really requiring their own compression scheme. Probably the best freely/readily available compression method would be the lossless compression codecs like flac, tak, monkey's audio, etc. These should consistently provide compression down to 60% of the original with no artifacts.
However, it would be possible to write an application that compressed the audio channel separately to the video channel and thus produce much higher levels of compression by using lossless compression on the video and lossy (say mp3) on the audio.
If there was enough interest in something like this I could produce something fairly quickly.
