Sorry if I wasn't clear of if I had typos in my posting. However this 
problem is solved. The error was in the hostname field of the recorded 
table. Once I corrected the old recordings to have the same hostname as 
the newer recordings, all the preview images popped up.

I didn't say this, but in my testing, the URL specified here:

https://www.mythtv.org/wiki/Content_Service#GetPreviewImage

was working for the newer recordings. I never got your image size string 
to work. I probably typed it in wrong.

Now I need to get the ASX and Direct Download links to work.
