I recently purchased an Elgato EyeTV Hybrid, on the basis of it having great Mac OS X software (EyeTV).
Device Details as seen from WinTV32:
Model 65018 Rev. B2C0
Tuner Model/Formats: Xceive XC3028 // (BG/I/DK) / DVB-T
Tuner Audio: Mono
Video Formats: NTSC ( M 443 ) PAL ( B G H I D K M N NCOMBO ) SECAM ( L L' )
Audio Outputs: Internal
External Inputs: 2
S-Video Inputs: 1
Of course tuner audio "mono" refers to analog reception only, with DTT it just plays the source bitstream so it is more likely to be joint stereo or stereo.
