New audio capture issue

After two years, my first problem. But I don't think it's Vegas.

Vegas 6d
M-Audio Delta 1010lt audio card
DSR-11 deck
XP Pro SP2

Audio on a recent shoot was recorded two channel. It is two channel when played on the DSR-11 deck and viewed through the video monitor and speakers independent of editing app.

Audio is clearly two channel when played back through two cameras.

But when captured via the DSR-11 (firewire) or a camera (firewire), the audio is mixed into one channel, and barely audible. All other video already captured on previous days and still in the system plays great, so not sure it's the sound card. This is also happening on four different DVCAM tapes. All play the right way independent of capture. It also does it on previously captured tapes that once were captured properly but now are not ... so it's not the tapes from that shoot.

I have never had two-channel audio captured as a single mixed channel before, and never had it barely audible ...

Could it be the firewire card? Doesn't seem to be the deck or the camera, as both will independently play it back as two channel and clear. It's only when capturing, and happens in Vegas and Premiere Pro 2.0

Any thoughts are appreciated ...

What camera was used to make the tape?

Did it by chance get changed to 32 instead of 48?

Yes,
what camera?

If it's a PDX10 then Vegas does have an issue.

Although by what you're saying this is now happening on tapes that were previously captured correctly, interesting.

When you say it happens in both Vegas and PPro 2 do you mean you've tried capturing them with Vegas and PPro and get the same result in both apps using that apps capture utility?

Have you checked in Vegas's VidCap where the audio source is pointed to?

Thanks for the questions. I solved it with Scenalyzer. Both PP and Vegas were capturing the audio very weird.

The camera was a PDX10. It is weird that the last time that camera was used and captured this issue didn't come up.

After using Scenalyzer, I imported the clips into Vegas and PP to check them and the audio was two-channel and crystal clear.

Can't explain it, but for $39 Scenalyzer saved the day!

I can explain it.

The PDX10 records in dual mono, the one and only to the best of my knowledge that does.

Windoz doesn't support such an audio channel and VidCap being a very Windoz thingy gets all twisted up over it.

I've also found SCLive the only way to capture footage from the PDX10.

I posted a similar question in about 2002 with V3 and a Sony 900 camcorder.
If I used the dual mic setting I had trouble getting both channels in the capture from V3.
The problem it appears is the extra flag for a DUAL mono tracks, Vegas just ignores one of the tracks for some reason.
I to then moved over to Scenealzer as you and have been a happy bunnie ever since.
