camcorder in a plastic bag and seal it 
tightly. Remove the bag when the air 
temperature inside the plastic bag has 
reached the surrounding temperature (after 
about one hour).

If you play back a tape recorded in HDV 
format, the image and sound may freeze for 
a while (about 0.5 seconds). 
This occurs if the HDV signals cannot be 
recorded or played back correctly because 
of dirt on the tape or video head. Depending 
on the cassette, this fairly infrequently 
occurs even if the cassette is brand new or 
is not used a lot.
If this freezing point is created while 
playing back, you can solve this problem 
and see the pictures by rewinding after 
slightly forwarding. Such a freezing point 
cannot be recovered if it was created while 
recording.
To prevent such a problem, use the Sony 
mini DV cassette.

heads for 10 seconds with the Sony cleaning 
cassette (optional).
