No audio on my camera with a rendered video

Ok, here's my problem.

I've downloaded DirectX 8 build 219 (the latest beta) on my
Windows 2000 system to see if the microsoft DV codec gets
better with the luminance/chroma problem.
The problem of lumi/chroma is gone (or near invisible) now,
but when I play back or print to tape on my Sony PC100e PAL
camera a rendered video, I've got absolutely no sound. But
in Vegas or in MediaPlayer, the audio sounds ok. And with
DirectX 7, the sound was perfectly ok.

The strange thing is that when I capture a clip and then
play back on my camera, the sound's got no problem.
I noticed in Vegas that the capture videos got "DV Audio"
for the audio codec, but the rendered videos got
the "Uncompressed" codec.
To me, it looks as if the rendered video got a strange
interleaved audio-video stream, because the capture videos
are DV type-1 with interleaced video and audio, and the
rendered videos seem to have no interleaced video and audio.
But in the video rendering option, I left checked the
interleave of 0,250 s.

So, where's the problem : DirectX 8, Vegas or my hardware ?
Again, all was perfect with Direct 7 (except the
lumi/chroma problem).

My softwares :
Windows 2000
DirectX 8 build 219
Vegas Video 2.0a build 323

My hardware :
Asus P2B, PII 400, 128 Mo
HD 10 Go 7200 rpm
Asus Firewire Card PCI-1394
Sony PC-100e PAL

Thanks for any suggestions, Amaury.

There are a number of bugs in DirectX8 beta having to do with PAL. We
are working with Microsoft to solve this problem.

Thanks Dave for your reply, but this time I think it may be Video
Capture that is buggy !!! (I've got the 2.0b build 39)

I've just installed PureMotion EditStudio 2.0.1.
It's got a DV copy program to copy AVI to tape through DirectShow
just as VV et VCap. And...it works ! The sound comes back on my
camera with my not so buggy rendered video !

EditStudio comes also with a small utility to convert from Type 1 to
Type 2 (AVI 1.0 and 2.0) and vice versa.
All the rendered videos that didn't "sounds" where Type 2 DV files.
When I convert them to Type 1, VCap plays them smoothly on my camera
with a perfect sound

So it seems VCap and DirectX 8 build 219 don't really like each
other...especially with Type 1 and Type 2 DV.

Nevermind, VV is just great, SF's done a fabulous job, I mean it !

Hope it will helps SF's developers.
Amaury.
