You're using a rather old version of ivtv there. Lots of problems were 
fixed in the 0.1.9 release. I believe problems with zero-length 
recordings were addressed after the version you're running, so I'm not 
surprised you see that happening. Have you considered trying the newer 
ivtv driver? It might make all your M179 problems history...
