Helped crazycat create the new crazyscan 1.0.0.6 drivers. Crazyscan is quite cool & popular with most users
These need his streamreader.dll files to work correctly. Confirmed this works well. Simply roll back the old driver 1.0.0.5 if finding problems with TBS Blindscan
This all should work with latest 1.0.0.6 driver on TBS download page though
But here is DLL's
http://crazycat69.narod.ru/sattelite/StreamReaderEx/test/StreamReaderExEx-BDA.rar
you can drop these Streamreader.dll's in programs like SmartDVB (&others) root directory and you can use blindscan functionality with TBS5990
i feel this file would be somewhere else on the interweb
