Hey guys long time no post. Anyway, I've seen a lot of glitch posts relating to dropouts, lip sync, pauses, etc on the HD-A1 using FW2.0. This can be fixed by doing the following: 1. Go into the HD-A1's Audio setup menu 2. Change Digital Out SPDIF from BITSTREAM to PCM (very important) 3. Use Analog 5.1 outputs or Digital HDMI 5.1 PCM for TrueHD/DD+/etc, as digital coax/optical SPDIF 5.1 will be disabled. 4. If you still have problems (they will likely be cured with step 2) change Digital Out HDMI from AUTO to PCM (optional) It seems that with TrueHD especially the re-encoding the decoded audio signal to DTS for output over SPDIF can overload player's processors and cause all of the errors mentioned in the topic line. This can be disabled for most as if you are using TrueHD you are likely using the HDMI or Analog 5.1 outputs anyway - using the SPDIF output for TrueHD is pointless since you won't get the full resolution out of it. Try it out, even if you don't use the digital SPDIF out you will be surprised that it cures your problem 99% of the time as the player will continue to re-encode to DTS for output over SPDIF unless you specifically tell it not to as is done in step 2 of the above.
