Video keeps failing harding test - working with stock - HELP NEEDED!!!

I have made a music promo, unfortuantely i have had it back from MTV twice now as it keeps failing the harding test (to test to see if it triggers epilietic siezures).

I am working with stock from the prelinger archives, which - to be honest - has been a nightmare to work with for various reasons.

The wierd thing is, the test has failed twice, both on different areas. I edited the video after it failed the first time, then it failed on a totally un-related area on the second test, which the first test didn't pick up.

I am getting "luminance flashes" between 0.5 and 2.2. Is there a way I can filter these out in the edit rather than get the video sent back again? The "luminance flshes" can not even be made out to the naked eye. I have changed the problem areas, then it picks up something else once I send it to MTV again.

Clearly something is happening when I export the video and get it transferred to Digibeta (same file, same edit - just changed slightly), OR - something is happening in Final Cut pro when I export to DV tape which is making this happen.

£60 a time for a digibeta transfer is becomming quite expensive. Especially if I get it sent back again!
