I recently bought an SF8008 since I thought it would be nice to upgrade to a faster 4k receiver.
From the beginning I noticed that the SF has a slow motion effect when changing channels, it last about 1+ seconds that the video is slowed down before the audio kicks in.
I find this quite annoying.
Also the channel change time is generally noticeably longer compared to my (dated) OsMini.
I find the de-interlacer of the SF not has good / sharp as the OsMini and the colours are somewhat too much 'in your face'
also images seem slightly over-processed.
I connected both receivers to a dual LNB and the tuner of the SF seems to be less sensitive compared to the OsMini.
It's not by a wide margin though but I had weak channels that would stutter on the SF but not on the OsMini.
Where the SF shines is, Multiboot, USB3, GigaBit (I measured up to full bus speed) , H.264, 4k playback and fast IPTV playback/channel switching.
(IPTV is not great on the OsMini)
Attached 2 pictures of the receiver's tuner performance on 'weak' channels.
The SF is generally not far behind the OsMini, so not to worry.
I think the SF is a good receiver but the channel switch slow-motion and the somewhat long switch times might not be for everyone.
And 'yes' I tried 6 different images on the SF ;)
