Hi,
This sounds like it is the Tape recording function that is at fault. Unfortunately, it's also one of the most difficult to correct without a scope and test jig.
However,
If it is more than 5 years old, it may be suffering from component failure.
In particular the Electrolytic capacitors in these small cams seem to fail first due to temperature and humidity changes. They can leak, dry up or corrode, so it may be worth looking inside at the control boards to spot any physical signs of deterioration.
This shows typical surface mount capacitors - silver cylinders with black segment denoting negative -

Visit www.funai-corp.com and under manual type your model to download pdf.

If I were you I would feed the video from the camcorder into your computer via the dv link cable where you can edit it frame by frame using ulead or similar.

tape guides are out of adjustment, need to have brought in for service.

Call 1-800-828-4040.....there is a defective chip that needs to be replaced and Canon will fix it for free. They even sent me free shipping lables as well....

If you want to have it done for free check the canon service note - it may help and will not cost you a broken penny. http://www.usa.canon.com/consumer/controller?act=PgComSmModDisplayAct&fcategoryid=227&modelid=9740&keycode=2112&id=48266

tape path needs to be aligned.

If the heads are TOO dirty, a head cleaner will not help. If you are cinfident enough to open up the recorder, then they can be cleaned manually.

Disconnect the VCR from the mains.

Remove the screews from the side and back (if applicable) of the lid.

Remove the lid.

Look at the large drum (set at a slight angle) If you gently rotate the drum you will see 2 or 4 small sensors set into the drum.

Tear of a clean piece of A4 paper about 1inch square.

Hold between thumb and first finger and rub the centre of the paper against each sensor in turn. Make sure the edge of the paper does not catch the sensor.

After each sensor check the paper for dirt (black marks) and change paper if need be.

Try a recording / playback.

Repeat if necessary.

For Models: CC4352, CC4362, CC4393. Your camcorder has a wide format recording mode that lets you make recordings compatible with the 16x9 format. When 16x9 is activated, the camcorder records black bars at the top and bottom of the picture to produce the wide-screen (movie) effect. This is also known as "letterbox" recording. Do not use this mode unless you have a compatible 16x9 TV. When played on a regular TV, black bars appear on the screen. If the 16x9 feature is activated on your camcorder and you want to turn it off, press REC/PAUSE to pause recording, and repeatedly press DIGITAL EFFECTS until no digital effects display appears.
