no recording

[DRICH]

I got windvr with a wireless USB 2.0 camera system. Ive reinstaled it 3 times. It is beter now then the first install, however when I hit the record botton it acts like its recording forever but when I open the files for veiwing, the clip is very clipped, 0 to 3 seconds long useually. I had one that was a whopin 2 1/4 mins. Its mostly 0 though.
If I uncheck "enable overlay" then hit the record, I get a caution "Recording in this resolution without viewing" Whatever that means. Still checked or unchecked dosn't change the lack of a recording.
I have ample HD space at about 170 gigs free with an external hd on the way at 500 gigs.
I get a good capture on all three cams just need to record it when im not home.
Any Thoughts?
