Thats the head switching point, and the video from the head just coming 
onto the tape isn't synchronized to that of the opposite head leaving 
the tape, hence the blur as the digital circuitry in todays vcr's 
scramble to play catchup.

Back when broadcasters were using the u-matic format, the consumer 
grades of that stuff did that too, but it didn't take us techs long to 
find the programming jumper pin on the system synch chip and set that 
head switch point fwd 3-6 lines, putting it down into the vertical 
interval and truely out of sight.  I've absolutely NDI if similar 
cheats can be done to the $50 vcr's being sold out of the warehouses 
today.  When I was refering to consumer grade, like the Sony 2800's, I 
was arbitrarily drawing a line at the about $6k mark as the broadcast 
stuff for 5 to 10 grand more, already had it moved out of sight.  
Selling point you understand...  But it was the same chipset, with 
marginally better mechanics wrapped around it.

stupid bounce rules.  I do use spamassassin too. :-)
