Swordfish HD DVD has one audio stream: “Dolby Digital Plus 5.1”. This movie played back flawlessly…
National Treasure BD has two audio streams. “5.1 Dolby Digital Uncompressed” and “5.1 Dolby Digital.” The movie defaulted using Dolby Digitial 5.1 and the movie playback was flawless. However when switching to 5.1 Dolby Digital Uncompressed the movie played back just as well, but with a stuttering static sound that seemed to be in the background. This sound would be too annoying to watch an entire movie.
Surfs Up BD has two audio streams. “PCM 5.1(uncompressed)” and “Dolby Digital True HD 5.1.” The movie defaulted to Dolby Digital True HD and was resulting in the same audio interference as National Treasure using 5.1 Dolby Digital Uncompressed and played back fine. When switching the audio stream to PCM 5.1(uncompressed) the movie played back flawlessly.
Casino Royal BD has two audio streams. “English PCM 5.1(uncompressed)” and “English 5.1.” The movie defaulted to English 5.1 and playback was flawless. I switched the audio to English PCM (uncompressed) and the movie played back flawlessly.
So, The BD titles seem to be following a trend of not being effected by the audio signal for video playback, but effected when playing uncompressed audio in one movie and effected when playing Dolby Digital True HD in another… Seems that there is no trend here.
Now for the HD DVD titles. I already tried Swordifsh, but I thought I would take a look at a few others since I was having most of my problems with HD DVDs.
Transformers HD DVD has one audio stream. 5.1 Dolby Digital Plus. Movie playback was surprisingly taking place this time, but was unstable and the audio sounded worse than what was experienced with National Treasure
Transformers BD* has one audio stream. 5.1 Dolby True HD. Movie Playback was unsuccessful, so I switched the audio to French 5.1 Dolby Digital and movie playback was successful, but unstable in the beginning.
Beowulf HD DVD has one audio stream. 5.1 Dolby Digital Plus. Movie Playback was successful, but the audio had the same effect as Transformers HD DVD.
Aeon Flux has two audio streams. 5.1 Dolby Digital Plus and 5.1 DTS. The movie defaulted to 5.1 Dolby Digital Plus and movie playback was successful, but with small artifacting. I swithed the audio to 5.1 DTS and playback was also successful with the same artifacting.
Batman Begins has two audio streams. 5.1 Dolby True HD and 5.1 Dolby Digital Plus. The movie defaulted to Dolby Digital Plus and movie playback was successful. I switched the audio to Dolby True HD and movie playback was fine. I almost noticed no difference.
Again it seems that the audio streams are not following a trend. I wish they had because that would of been an easy diagnosis. I have many more movies and I tried to select a few that had a divers palot of audio streams. Also, 3 weeks ago I tested a few of these movies and was experiencing different effects in playback. For example I could not get Batman Begins to plat at all 3 weeks ago.
Anyways. There are your results concerning different audio streams.
