What type of audio encoding is made with the HD PVR?
The HD PVR supports AC-3 (5.1) or 2 channel AAC audio capture. AAC 2 channel is received using RCA audio inputs, or SPDIF when set to PCM. If using SPDIF with bit stream audio, you will get 5.1 AC-3 Dolby Digital. DTS audio is currently not supported. Currently, the Arcsoft TME application will only support editing from the beginning or the end of a clip to preserve 5.1 audio. Any editing or cuts made in the middle segments of a clip will result in the audio being transcoded back to 2.
