Two issues of concern: 1) Audio & 2) External Monitor

These appear to be seperate issues with DVDA 2.0a.

First the audio. I render my avi file to be used for the DVD buring process with the audio format: 48,000 hz and 16 bit (using Vegas 5, of course). However, when I go to play back this very file within the DVDA 2.0a program, I need to configure my audio hardware to 44,100 hz. Is this normal??? I thought audio files to be used for DVD needed to be rendered to 48,000 hz/16 bit?!?!?!? I tried searching DVDA's help files and could not find anything regarding this issue. (Below, you'll find my computer configuration and hardware used during audio/video editing).

Second, the External Monitor option. Simply put, I can't get it to work consistantly like I can with the Vegas 5b program and even the Sound Forge 7a program! When I plug in my Panasonic AG-DV2000 MiniDV device, the DVDA 2a program SAYS that it recognizes it when I click on "Options/Preferences/Video Device". It recognizes the OHCI Compliant IEEE 1394/DV device and further states in Details: "Hot pluggable device" & "Device connected". Also, under options, I click on "Preview External Monitor", but it doe not always show up on the external monitor screen. It's not reliable like the Vegas and even the Soundforge 7 program. Is this a known issue??? Is there a better way to configure my computer so that the DV2000 is better recognizable by DVDA2a???

Otherwise I have no other complaints/concerns. . . so far. The bottom line, I'm able to burn DVD's (-R & +R) without any major problems, except for the ones noted above.

Here's my computer set up with external devices included:

*** Dell Workstation 650
*** Intel Xeon 2.8 Processor
*** 1 GB RAM
*** Two internal SATA hard drives that came with the computer: Drive C = for programs; Drive D = for temp files for various programs and wav files for softsynths, etc.
*** A 3rd internal Ultra ATA hard drive (with its own controller) used for audio/video editing.
*** One external 1394-based hard drive using a Granit Digital FireVue casing used for audio/video editing.
*** NVIDIA Quadro FX 500
*** XP Pro SP1
*** Motu's 828 MK2
*** Motu's MTPAV (USB)
*** Panasonic's AG DV2000
*** JVC TM-H1375SU external monitor
*** Note: I network this computer to my aging Dell Workstation 420 which is used primarily for archiving and internet access.
*** Note: My Dell Workstaion 420 has Windows XP Pro SP2, which has caused problems with my two computers networking together. I disabled the Windows Firewall associated with the SP2 and all seems to be fine.
*** Note: Because I do primarily audio sequencing & recording, I have the MOTU 828 MK2 set to word clock, synced to the MTPAV. Could THIS be an issue for the my audio concern? (But I STILL need to set the 828 & the MTPAV to 41,000 hz in order to correctly hear the avi file which is rendered as mentioned above.)

THANK YOU in advance for any feedback or suggestions that you my share to me.

Regards,

Ted Fiebke

The external monitor is a known issue. Here is my workaround:

Workaround to External preview stopped working

I am not sure I understand your audio question, but you are correct that DV audio and DVD audio are 48 kHz.

First, thank you for the quick reply! :) I actually did what you suggested before I started this thread. This particular "workaround" does seem to work! :)

Regarding the audio question. . .

Why must I set my audio device (the MOTU 828 MK2) to 44,100 hz in order to correctly hear the avi file with its audio rendered at 48,000 hz??? Should I not be able to hear the avi file with my audio device set to 48,000 hz?? This particular issue doesn't effect the end result, a succesfully "burnt" DVD. But I shouldn't have to adjust my audio device from 48.000 hz to 44,100 hz in order to correctly hear an avi file that's already set to 48.000 hz.

I'm confused!

I'm afraid I don't know anything about the MOTU 828 MK2, so I can't answer your question. Maybe someone else will chime in.

UPDATE:

I went into the 828 MK2 Audio Console and changed the setting from "Word Clock" (with MOTU's MTPAV as the source) to "Internal", then set the 828 MK2 to 48,000 hz. Finally, went to a recent project used in the DVDA2a and played back the avi file (with the audio set to 48,000 hz).

For whatever reason, the setting within the 828 MK2 Audio Console was switched to 44,100 hz. My guess was this was done by the DVDA2a program. It's like the DVDA2a program wants ONLY the audio device to be set at 44,100 hz.

I'm stumped.

Seems like a glitch to me. . . at least between DVDA2a and the MOTU audio device. Understand that no other programs does this when playing an audio or avi file set at 48,000 hz. Also understand that this issue is just a minor inconvenience to me. I am otherwise happy with the end results provided by DVDA2a: a functional DVD.

Just wondering why this is happening. . . . (?????)
