fortuna,
The S660 works very well, it's a marginal slower then the S470 PciE, cause of extra latency of USB, but zapping works very well.
MP has diseq support in upcomming SVN or RC: 0002552: DiSEqC support is not working for TeVii cards - MediaPortal Bugtracker
Currently running the S660 (2 of them in @ system), for 8 days without crash or reboot.![Stick Out Tongue :p :p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I didn't test it on an ION system as TVService / MP; but it should be no problem. Maybe to improve zapping speed a faster HDD / SSD.
