Yep, that's the same filter I'm using and it works well. Here's a link to a short test clip I shot under tungsten lighting and you can see it working. The IR problem is also happening outside in sunlight:

Any news on the Tiffen IR filter?

Hi there,
That filter has reported green vignetting issues. I don't have one but have heard lots of reports of it on full wide shots. Hence why Tiffen are meant to be bringing out the new one. No green casts!

This may be unconventional, but there are Flare adjustments in the service menu, which might be used to skew the blacks away from reddish casts. From my reading on what flare adjustments do, they seem to compensate for the contrast of the lens when bright light is hitting a portion of the lens. Flare affects how the sensor response to the color cast of the black portions of the image.
Granted, it was not the intent of this flare adjustment to correct IR contamination, but there might be some margin of adjustment that could be done to compensate for the color casts with some black materials. It might be the option to crush some reds that are near-black, and end up with slightly more contrast, but it may suppress some red if done successfully.
Really though, why don't cheap consumer cameras have this problem? My V1U had perfect blacks. So does my Canon HV20. I don't see why the EX should have gross color inaccuracy like this. This is really in the realm of a Sony in-warranty fix with no statute of limitations.

My guess is that is a planned obsolescence type thing. Pro's pros will not tolerate the IR contamination, and go for the more expensive model that doesn't have the problem. They can't just give you an EX1 that works perfectly now could they? What would be the reason for buying a more expensive camera?
The same thing happened with point & shoot sensors. Around 2004 you were getting awesome sensors in p&s cameras, which affected the DSLR market. So they reduced the size of the sensor, and uped the MP rating, and instilled noise reduction to clean up the mess somewhat so the armatures were happy, but the pros could see the swirly looking swaths of grass or background detail. This happened with the DSC-H9, a camera with DSLR features but point and shoot handy as far as live LCD goes. Awesome camera - but hobbled chip smaller than previous chips.
It's a bit of a game that Sony plays I believe. And good luck getting them to address any design issue.
