    1.1.28271
    – Streamlined transport data handling code for improved stability.

    o Eliminated the queuing of transport data and deprecated the “FlushOnChannelChange”
    registry key.

    o Minimized variance in channel change times. Expect channel change times of ~15
    seconds with the internal blaster.

    o Eliminate “weak signal” messages due to transport handling issues.

    Note: Because the HDPVR utilizes a hardware H.264 encoder, it behaves differently than typical
    tuner based devices.  The HDPVR encoder must be reset whenever the input video resolution or
    bit stream audio type changes.  Additionally, the HDPVR encoder may reset due to input video
    dropouts or errors in bit stream audio.  The HDPVR stops streaming at the onset of the reset and
    resumes ~ 2-4 seconds after the return of stable audio and video.

    MCE displays a “Weak signal” message when it sees” bad” or “no” transport data from a source
    for a predetermined time.  The reset time of the HDPVR encoder appears to fall just within the
    threshold to trigger a weak signal message.

    The changes in V28271 address disruptions in the transport stream artificially induced due to
    software issues.  Weak signal messages may still occur:

    1) During channel change
    2) During audio/video dropouts from the source
