Display active bitrate onscreen

I have two questions.

First I have this model #: WDBYMN0000NBK-HESN bought at Bestbuy last week...so very new.
Which "version is it"? I see gen1, 2, 3 live and plus and want to make sure I get the right flash module.

Second and real question...One thing I love about my Sony bluray player but don't see as much as I'd like to on other players is the ability to show the current bitrate on screen (display button). It shows both the audio codec and bitrate and video codec and bitrate. Is that possible with any of these firmwares updates?

The standard "bitrate" in the current WD firmware looks to be the average for the file and is also usually very wrong...for example my STAR WARS Episode IV bluray to mkv remux file has a bitrate of 67,656 Mbps. Yeah, that''s nearly 70 Gbps...can't possibly be right. Also, when you hit "options" on the remote the movie stops playing...so it certainly can't be an active number.

I've checked the wiki page and searched "bitrate" and something about "appz" came up by rezmus which I think is what I am looking for but from the page I was won I have no idea what it was applicable to.

Thanks for any info/help.

Something that is odd ....

This site list's the Bitrates for the Star Wars Blu Ray Collection ... and all of them are about "Half" the bitrate of your's :shock:

The Phantom Menace has an average video bitrate of 28 Mbps and average audio bitrate of 4.6 Mbps.
The Attack of the Clones has an average video bitrate of 29 Mbps and average audio bitrate of 4.0 Mbps.
Revenge of the Sith has an average video bitrate of 30 Mbps and average audio bitrate of 4.7 mbps.
A New Hope has an average video bitrate of 31 Mbps and average audio bitrate of 3.9 Mbps.
The Empire Strikes Back has an average video bitrate of 30 Mbps and average audio bitrate of 4.6 Mbps.
Return of the Jedi has an average video bitrate of 30 Mbps and average audio bitrate of 4.5 mbps.

I know that's my point. The software native to my device is messing up the calculation...it's not off by half or 50% it's off by 5000% becasue it's listing as Gbps not Mbps, rather tens of thousands of Mbps.

Weird.

So it's a gen4 device...thanks for reply.

Some countries reverse the meanings of the comma and decimal, so 67,656 Mbps could mean 67.656 Mbps. This is within the bitrate Blu-ray is capable of. From blu-ray.com's Blu-ray FAQ:
1.7 How fast can you read/write data on a Blu-ray disc?

According to the Blu-ray Disc specification, 1x speed is defined as 36Mbps. However, as BD-ROM movies will require a 54Mbps data transfer rate the minimum speed we're expecting to see is 2x (72Mbps).

One other possibility, though it wouldn't explain a near-70 Gbps rate, is that it could be reporting the HDMI bitrate, which is uncompressed and therefore always much higher then the rate coming from the source. Hdmi Bit Rate Calculator shows a chart of bitrates for different resolutions, frame rates and color depths. The maximum rate shown is 8.91 Gbps.
