Thanks in advance
OTA ATSC is already encoded (MPEG2) when transmitted by the TV Stations. The tuner card performs no encoding, just grabs the stream and writes it to the Hard Drive. What you choose to do with the recorded material (re-encode to XVID, h264) is done by software and has nothing to do with tuner cards.
You must be confused by analog capture cards. An analog signal is what needs to be encoded, digital signals have no such requirements.
