Sorry I won't be able to view your clip until I get home this evening. Here's a thread from last week on the same topic, though:

No definitive answer yet, but kind of suspect that it has something to do with over-saturation of colors or a compression anomaly.

Was this shot in 24P, 24PA, 30P or 60i? I usually see this problem in overexposed areas of red (sometimes blue) generally when there is a frame rate conversion or deinterlacing. The best thing to do is to watch your expoure and settings to begin with. It looks like the clip is color corrected. BE CAREFUL WITH REDS!! This is not an XL2 prob, it is a DV problex, the DVX is actually the worst offender. Sometimes Magic Bullet and other programs can make the reds go crazy. If this happens to me I curb the reds, output THAT file and color correct the file with supressed reds.

This problem is also accentuated when viewing on an LCD or other progressive source like an HDTV. One thing you can try is a chroma blur on the red channel...
