I'm still grossly underwhelmed by my first New England winter. (I'm  
in Tyngsboro, MA, just south of Nashua, NH). I even drove my sedan  
(Volvo S40) to work today, rather than taking the family people mover  
(Chevy Tahoe).

Are you running the latest firmware on your HDHR? The original  
firmware on mine (got it just a few days ago) had lots of video  
artifact issues that are completely gone w/the latest firmware.
