Display Storyline/Rise course on touchscreen TV

Hi, 

I have several courses (some Rise, some Storyline) that my company is planning to display at a congress on large touch screen TVs where the aim is to get stand visitors to run through the course before they go home and complete it for professional development. We are unsure of internet connection and reliability as their is the potential to have thousands in attendance hence going for an offline version.  

As advised elsewhere on the website for offline use I've published to "CD" and uploaded the files onto a USB stick, but I'm unable to load these through the TV. They work fine offline on tablets and laptops I'm guessing as they have HTML/browser capabilities. 

Has anyone else had experience of having to do this? Does anyone have any suggestions of what else might work before we have to explore other options? 

Thanks in advance!
