What were your settings? What format was your source footage?
-
Ok….do you have audio on the menus then?
-
are they motion menus?
-
You said you had many menus? How many and are they motion menus? Whats the total length of them?

DVD-ROM is a different format than DVD-R,DVD+R or DVD-VIDEO. The latter all play VIDEO_TS folders on a set top. DVD-ROM is a computer only format (like CD-ROM).
There are many players which will have trouble playing DL media. The only media that should be used is Verbatim DVD+R DL. Which tool are you using to author? Try the Verbatim media…see if it helps.

I believe in Bitvice since it one of the few Mac encoders out there – and its a good price. I have yet to try the Cinemacraft plug-in but I”ve used the PC version for years now.
You have bandwidth limits that need to be considered in DVD. 9.8 for video and 10.08 for audio and video. Since all encoder will sometime spike over the limits you set, along with your uncompressed audio (which takes up 1.5 mb/s of space) you certainly went over that limit.
8-9 mb/s is too high. There isn’t a DVD compressionist in the world who would tell you to crank up the max bitrate settings to the max. Keep your bitrate settings at a conservative level and always check your bitrates with a bitrate viewer afterwards. Use uncompressed audio but only if you take that 10.8 limit into consideration. Always use a bitrate calculator before you encode.
I dont’ use Compressor since its frankly a terrible encoder at lower bitrates. Compare the 2 by doing a short test at VBR 3mb/s with some moderately fast movement in the source. Not that you’ll be doing VBR @ 3-4mb/s alot but it shows you how much better Bitvice can be a lower bitrates. If a client comes to you and insists they need 4 hours on a DL disc, you can now tell them – “OK…I can do that” 🙂

Are you using AC3 audio? 🙂 uncompressed audio takes alot of bandwidth.

There’s an NC-17 setting which puts a value of 7 into SPRM 13. Check in the manual for each setting. It doesn’t matter which GPRM
Also make sure the client knows this is a waste of time unless the parental mode is set correctly on the player….something nobody does. 🙂

I doubt it would impact the quality. It all depends on who your target audience. I would say, that for many concert tiles, it would possibly mean more to the audiophiles who purchase such titles. Most folks don’t really care about the quality of audio as long as they can hear it. However, its our job as professionals to make that title the best it can be.
So you have a trade off now. Personally I would take the 1.5 mb/s hit on my audio to save it for my video….especially where space is limited) Listen to a quality AC3 track on a good 5.1 set up and I’ll think you’ll like it:)
I dislike Compressor. If you can, try another encoder and test your results. There are several good encoders.

The most i’ve done for a DVD-9 was almost 5 hours but this was only because I used an encoder with segment based re-encoding and pain painstakingly adjusted bitrates to make the client happy.
According to my calculator you can use a bitrate of ABOUT 5.9 max for three hours of footage with a couple motion menus. DONT USE uncompressed audio for this title…your looking at a video bitrate in the low 4 range then. AC3 is great…uncompressed audio is overrated for DVD 🙂
You never indicated which encoder you plan to use. if you have a budget…find someone who used a good encoder like Cinemacraft for example.
