Bladerunner Pro problem
It has been mentioned a fair few times on here and this appears to be the solutoin (not having the problem myself, but seems to fix everyone elses)
The issue appears to be that some people Internet Connection is to fast/slow/error ridden, or whatever other reason you can think of and that the older (and slower) version of TVHarvest has less problems in these situations...
Hope that helps.
Schlep.
