iI have been through Hauppage, Avermedia and Silicon Dust stuff over the years. The SD ATSC tuners are the least sensitive and the Avermedia the most. Before everthing went digitial a lot of stations were broadcasting digital at lower powerlevelss. Once the analog was gone the FCC allowed the stations to boost their wattage. So there was a time I cursed the SD tuners to death because no matter what they just did not pull stations in sufficiently to work properly even with a very good drop amp. The Avers would work, the Tivo would work, not the SD HRs. After the local OTA went to full power the SD Tuners are mody appliance like tuners I have. They just work and they have been laying on the floor, two of them attached to a 4 port Motorola BDA for several years with zero attention. They just work... You literally forget about them. The Ceton cable tuners have come a tremendous long way but they will never be as robust as my now 5 year old HD HRs.......... I gave 2 of them to my brother and he had one AC adapter fail. They were of the same vintage and have been in service for many years as well
I do seem to recall the Avermedia suff being flaky about showing on PCI-e bus..
