My System: 1.2M Channel Master, C120 Invacom 0.3 LNB & Feedhorn, with Humax HDCI2000. 68.5E - 61W |
Just wondering how other peoples receivers fare with low SR channels that use DVB S2. My receiver (Humax HDCI2000) is only supposed to receive S2 channels using symbol rates between 10000 - 30000, but i've succesfully locked onto channels using symbol rates as low as 5000 and even 3404, but not been succesful on one using 2308. Just interested to know how others do? | ||

A good find. I think Humax are really only considering HD capability. Llew | ||
