Yup. We discovered this issue a day after release.
vp3.1 videos/streams are still playing ok, but not the older vp3.0 ones.
It's happened as a result of the security vulnerability fix in 5.621
We'll fix it for the next release and I might even post the fix here.
I upgraded to 5.623 and the VP3.1 streaming issue still hasn't been fixed. The workaround using the old version (5.601) of nsvdec_vp3.dll cures the video stream playback issue but I'm disappointed that a fix hasn't been implemented in last couple of releases. Are there any security issues in running the old dll to enable viewing of VP3.1 shoutcastTV streams?
