| | Posted: | | | | Just got my BD copy of Iron Maiden: Flight 666, and there are 3 audiotracks on the movie, and also the full lenght concert. Choises are:
1. English 2.0 Stereo (easy choise, not selected by me)
2. English DTS HD Master Audio (5.1 channel, not 7.1)
3. English PCM 5.1
So what's the "best" format. Haven't had time to compare them yet, but want some input here. And what's the difference between the two tracks (bitrate etc) (point 2 and 3) | | | "What's God?"

| | Posted: | | | | DTS HD Master Audio and PCM 5.1 are both uncompressed formats and the bitrates will be high, whereas the 2.0 stereo is probably just compressed Dolby (?) and the same low-bit format that has been used on DVD's since the beginning and will sound less dynamic.
I would choose either DTS HD 5.1 or the PCM 5.1 track, which will both be virtually identical. Choose whichever one your receiver can handle. Most older receivers can handle PCM, while DTS HD is a newer format. | | | | Corey | | | | Last edited: by Katatonia |

DTS HD Master Audio and PCM 5.1 are both uncompressed formats and the bitrates As far as I know DTS-HD MA is lossless compression codec and PCM is uncompressed. End result is the same, but slight technical difference. |

Well yeah, technically DTS HD and Dolby TrueHD are both more similar to a "zipped" file. They're smaller than an uncompressed file, but when they're unpacked they are bit-for-bit identical to an uncompressed track. They just take up a little less disc space. | | | | Corey |

| | Posted: | | | | Just on general principle I'd go with the uncompressed PCM, though, in case something went awry in the compression of the DTS. | | | | "This movie has warped my fragile little mind." |

| | Posted: | | | | I'd check the bitrate. Often, when you see lossless & PCM, the lossless is a higher bitrate. |

I think you're confusing lossless and uncompressed. lossless is technically a compressed format as mentioned earlier, but it's more akin to a "zip" file (which is lossless when unpacked) and will have a lower bitrate for that audio track on the disc. The end result of a PCM and an unpacked lossless track should be virtually identical. | | | | Corey |

| | Posted: | | | | personally, as long as the disc has lossless I don't care. But...If a disc has PCM I usually go with that. Two examples I can think of is Superman Returns, and Spiderman 3. Both PCM tracks are better than thier truehd counterparts. | | | | The artist formerly known as TylerDurden_73 |
