If the aspect ratio is the only problem with mythtranscode you might try 
(I haven't)

mythffmpeg -i /store/1017_20171001114200.ts -acodec copy -vcodec copy 
-aspect 16:9 /store/Movies/DM8x01.mpg  (or .avi ?)

or you could try playing the output from mythlink as a video.  It looks 
as if the .avi default settings are for an early phone.
