I am too lazy to proof your math
. Maybe someone else can do that. But I don't think we need to prove that BD-25 holds less content than HD DVD-30 at the same rate, do we? The issue is that if you use higher rate, as is the case when you throw in a PCM track, then the capacity deficit becomes higher compared to HD DVD-30. Likewise, the storage gap of BD-50 to HD DVD-30 is diminished as a result, without gaining you any quality advantage over lossless audio. And compared to high rate DD+ (another codec not standard in BD), then you have even a bigger gap.
And hasn't it been proven that most BD25 releases are great releases, capacity not withstanding?
Great meaning what? None of them have Picture in Picture so if you are comparing them to HD DVD titles, well, they left out something that would take out bandwidth and space. And many lack extras that HD DVD counterparts have. Indeed, many HD DVDs have the same extras as the deluxe DVD set.
Coming back to the question of using LPCM on BD25, a Dolby TrueHD FAQ stated that 6-channel, 16-bit 48 Hz runs at 4.61 Mbps. So that means a BD25 can have a sustained 20Mbps for video for 133 minutes. That's 20Mbps for MPEG-2, or VC-1 or AVC. [size=4]Isn't AVC at 20Mbps ain't that bad, paidgeek?
The fly in the ointment is that TrueHD is not standard in every BD player. And hence the pickle they are in. If they used TrueHD tomorrow on all of their discs, there would a large cry from everyone who bought the Samsung, etc. which can't play it. They saved a few cents that way, and messed with your suggestion as a result
