The first one looks like you are triggering on noise or runt pulses.  What 
does it look like if you set the trigger level much higher, say half of the 
full voltage?

One thing to try...  Switch to single shot mode.  Turn the room lights way 
down.  Your eye will remember the picture for long enough.

The simple solution is to get a digital scope.
