If you have two Clips on the Timeline, and there are adequate Handles, then you can add the Cross-Dissolve Transition between the two.
Is this what you are doing?
Are you having an issue with the Cross-Dissolve Transition?
For a discussion on Handles, see this ARTICLE.
I have read the post that you linked me to and I have bookmarked that thread as well because the information looks very valuable to a newbie like myself. Seems that I need to get a better understanding of Handles I'll be reading the link in the link that you provided above and hopefully these will get me up to speed....thank you for your help Bill.
Sounds like you want a cross dissolve?
Put clip 1 on track 1 and clip 2 on track 2.
Slide track 2 a bit earlier by the length of the dissolve effect
fade in the top track and you automatically get a "dissolve" effect
Adjust the audio levels around the transition so you dont get an overlap - that often sounds wrong
You can drag the little markers in the video and audio level lines to adjust all tracks.
