I've seen one on Myanmar (I own it, possibly vhs tape not cd/dvd), but not one on the two nations combined.
I haven't gone to Amazon to beat you to it, but I am tempted. If it is a stock line, I can buy my own. If it isn't, you buy it without a contest, then when you have tired of watching it, send me a pm on how to buy it third hand.
The Myanmar one was fairly much a promotional video for the Pandaw project, with some history, and a lot of evocative scenes to make you want to book on a voyage.
The Myanmar paddleboats were fairly boxy and similar (mainly sternwheel, some side wheel). The Bangladesh ones have more style, but there are only about four in the Bangladesh era; there may have been more when it was part of India, then part of Pakistan. My photos aboard PV (formerly PS) Ostrich are in their own thread, with photos of most of the others taken as we passed en route.
