Field Swaping every 2-3 mins with WinTV

[CocoPops]

Yes, this might sound a little bit strange, but I'll try anyway...

Step 1 : Capture a 704x576 movie with Vdub or AVIO (cap card is a Hauppague WinTV Theater using lates VFW drivers).
Step 2 : Konvert the clip using Tmpeg 12 to MPEG2 (interlaced)
Step 3 : Playback on a Hollywood+ card

Normaly this works just fine, but I have now a strange field swapping every 2-3 min.
So This means it playback fine for a couple od mins, and then the field order is swapped.

What I DO know is that it's not the Hollywood+ card, since I have other Interlaced MPEG2 files and the playback is fine there...

I would just like to hear if ANYONE have ever heard of this problem....

Right know I'm running Win2000 and I really don't want to install Win98se if there's a easy fix for it.

I'm pretty sure it have worked before, but I have just reinstalled Win2000 (clean) and the problem is still there..

Maybe using another driver would help ?

It's not strange at all.
I have a WinTv PCI and a WinTv PVR and both models have the same problem.
I capture at 768*576, YUV2, Huffyuv.
During long capture (more than 5 minutes for Hauppauge support), randomly (but often every around 10000 frames), the video stream shifts incorrectlty one field, so the following frames are composed with one field from previous frame and one field from the right frame.
And around 10000 frames later, back to normal. Etc.

For long capture movie, I have to check every 1000 frames to search a problem and find the exact beginning frame and ending frame to make a decent frameserver with some filter to correct the problem (PAL Deinterlace, sometimes with swap field, sometimes without).

For a 2 hours movie like "A phantom menace", I have to handle 9 frameservers to have a correct video stream. And the resulting svcd was very good.

For your knowledge, Hauppauge support is aware of the issue but seems to be unable to correct it.

Regards.

Is there a chance that it might be a motherboard problem ?
I have a ABIT KT7A-RAID and it has a VIA chipset.

Or has it something to do with Win2000 and it's "funny" way of assigning IRQ's ?
On my system the ATI RADEON, Hoontech Soundtrack, Creative DXR3 and ofcouse WinTV Theater is sharing the same IRQ

Everone says that's normal, since it's a ACPI enable motherboard I have...(but I still don't like it).

So I might buy myself a Intel motherboard and CPU....

Anybody tried the German capture software out ?
I was capturing with WinTV2000 using DivX (No frame loss) however it needs converting later to mpeg.

This German software, captures to VCD.mpeg and works very well with this "basic" WinTV PCI
