scenarist authoring error

[guboogi]

i'm trying to author a DVD and it says:

Error: Total bitrate is too HIGH. Please reduce the stream bitrate or the number of stream.
Error: Multiplex is failed.

i'm thinking this is either:

1) when i did the multipass vbr in CCE i used a max bitrate of 9800. is this too high? should i use something like 9300 or 9400?

2) on the doom9 guide it says that it uses PGC1 as a template PGC. so if PGC1 is supposed to have two audio tracks but i'm only using one of them, do i need to make a dummy second track? (the entire dvd has only 1 PGC)

can anyone lend some helpful input?

The MAXIMUM total bitrate is 10.08Mbps. If you encode your video at 9.8Mbps, this only leaves 280kbps for your audio (most stereo audio is encoded around 384kbps). This leaves no room for anything else, either (no subpictures or extra audio tracks). I like to keep my maximum video at 9.0 to 9.5Mbps just for these reasons.

just an odd note (SLK001 is correct above) -- i just made a dvd sampler movie dvd for a client for some new films and they wanted super high quality so i went for broke and encoded at 8800 plus a 384 ac3 6channel sound .. both snell and wilcox and m-probe shows the data rate never goes over 10.2 m -- highest is 10.16 .. by all accounts this is a legal dvd and it plays fine in both my pioneer 7400 and in consumer pioneer 343 and others -- but the client bought a stack of JVC dvd players- dont know the model which they sent out to thier clients with the disk and I just got a report that 1/3 of the players skip at the highest bit rate parts - so they truied a different model and it alos skips (jvc also) -- but toshiba and pioneer and apex all play fine (but one sony skiped also) ,,,, of course this is a player issue but non the less it means i have to re-make 200 disks at my cost.

point is - YES high bit rate should always work because by dvd specs all players should be able to play contin. max bit rate -- but it is evident that some models can not do so ... so do a check first .,,,

these disks had macrovision -- but that doesnt seem to be the factor ..

how does one calculate the total bitrate, then? is the maximum bitrate equal to the video bitrate and the audio bitrate AT ANY GIVEN TIME? for example, if i have a video stream of 9.5 Mbps and two audio tracks of 384 kbps would that put me over (10.268 Mbps) or do the 384 kbps audio tracks only count once?

also, say i have a film that has 5 PGCs, as long as each PGC has video+audio that is under 10.08 Mbps, i should be fine, right?

thanks. :]

The maximum bitrate is calculated using ALL of your substreams (whether you are viewing/hearing them or not). So, if you have a 9.4Mbps video stream, and 3 300kbps audio streams and 4 10kbit subpicture streams, the total would be 9.4 + 3x0.300 + 4x0.010, or 10.34Mbps, which would exceed the spec.
