Any chance for WD TV HD Media Player (Gen 1 & 2) to support RMVB file as AVI file is too large and secondly very lazy to do mass conversion.
Your post sounds more like an Idea or a Feature Request. The best place for this is in our Ideas Lab. This way someone from WD will be sure to see it. However, I would search first and make sure that there isn’t another idea similar to yours that you could add your post to and vote on.
