All my movies are .mpg format with a few .avi but Roku media player doesn't support that. I know I can convert to .mp4 but that is a lot of work for several hundred movies. Is there anything I can do?
thanks in advance
You could look into transcoding on the fly with something like Plex. Your pc will have to be powerful enough and on while streaming.
The answer to why usually comes down to them paying to use proprietary codecs.
