Yes the 5520 is good in windows if you have a current TP list. As far as blind scanning it sucks.
Believe me. I've looked here and there.I guess what I am saying is blind scan with a good STB, Save your TP list to a thumb drive and copy it to dvbdreams transponder ini file. Do a manual scan of the ABC and CBS Tp's on 95 and 99W for ABC and 89 and 97W for CBS, you will be watching glorious 4.2.2 feeds.
