AZBox makes several receiver models that have ATSC/QAM and DVB-S2 record capability.
I've been testing an AZBox HD Premium receiver.
Tuner 1 = DVB-S2 (standard)
Tuner 2 = ATSC / QAM (user installed)
Hard drive = 1TB (user installed)
The box has HDMI, and component video outputs. 4:2:2 video is supported.
I can make High Definition recordings from C/KU "Free To Air" (FTA) satellite channels, ATSC "Off The Air" (OTA), and unencrypted QAM digital cable channels.
The recordings are .TS (Transport Stream) format. The receiver is fully networked. NFS and SMB (Samba) and FTP file transfer protocols are supported. The recorded files are fully accessible from any device connected to my local area network.
The ATSC firmware is in a beta state, but it's usable. The FTA firmware is a little better. (The developers are in Portugal and don't have ready access to ATSC signals).
I own the box and it's fully operational. I don't have to pay monthly rental fees to TIVO, Cable, or Satellite companies to make recordings. I use the box just like a VCR.
The AZBox also functions as a Networked Media Player and will play back virtually any file format as well as streaming Internet Video feeds.
Internet Cost $325 (includes shipping)
