SmartersPro has not worked for a couple of years on the Roku. Roku is not very friendly to IPTV as most of the IPTV services are not legal/legitimate.
Not adviseable to install any channels in this manner via developer mode in Roku. This is not welcomed as other side-loading streaming devices. ( Do not look at developer mode as the same as side-loading.)
