@Bob2050x - I appreciate the info, unfortunately it doesn't help my situation. My files are all .mp4 already with modern encoding and only a single audio track. I tried several different encoding methods with no luck, but I must say I'm not willing to re-encode 683 files. The part of this that makes me the most angry and disappointed in Roku, is that my OLDEST unit of the 3 I own isn't even a year old. I know people are full of hot air most of the time, and the user agreement probably has some language that would make it difficult, but I'm really tempted to file a small claims court case against Roku. Maybe if they were served with a laws**t (They actually block that word!) in another state they would consider listening to their customers and not just rendering their product useless and ignoring them. It may be worth the $50 or so it costs to file the case. I must say, I'm also sad to see that there is no response to these recent comments from a Roku representative. This could easily be construed as an admission of guilt in the situation as they clearly are choosing not to defend their actions. Taking money from customers, then ruining their devices is a very unethical thing to do. Hopefully they'll step up.
