Reading both TV Connector guides (original and version 2) on page 15 of the version 2 guide says the connector can receive and transmit Dolby Audio, stereo or mono audio signals. The original guide says can only receive and transmit audio in mono or stereo and you have to change the TV audio setting to stereo (PCM).
Are there any pros and cons connecting power with the USB cable to the TV verses using the AC adapter?
