Perhaps the audio is panned to the left channel.  try changing the 
audio pan on the cloned audio clip.  Triple and quadrupling the number 
of tracks might create a more robust sound.

Are you selecting cross dissolve?  Sounds like you are trying an 
additive dissolve.

Not very well.

Go back to the same location and record ambient sound.  It will most 
likely sound very similar.

You need to ensure that the color is corrected to NTSC standards in 
Photoshop and the broadcast quality standard is set to conservative.  
100-110 ire units.  If the tape is to be telecast over a licensed 
broadcaster the maximum IRE should be 100 and minimum 7.5.

A VHS layoff will look even worse.  Colors muddied by lack of NTSC 
compatibility,  inattention to signal quality, and stills that don't 
move all make for a pretty crappy signal.  (768x512 is not a size that 
lends itself well to panning and scaling)  Images that were 500 lines 
are reduced to 240 lines or less.  Dubs from the VHS master or 
transfers to a cable systems server will result in further bleeding of 
color and a symptom called cartoon effect which blends slight color 
differences into a single flat color.

But then some clown will just say.  "well, its just access television"
