I see. FWIW, it also happens to me from time to time. When it does, the downloaded video plays garbled in CuteTube but fine in Media Player. I have another annoying bug. I thought I'd already reported it but I cannot find it. Sometimes I get double audio. Like an echo, only at the same intensity as the original and with about 2 seconds delay. Steps to reroduce: 1. Go to Search, type your search string and hit the Search button. 2. Play a random search result. 3. Repeat step 2 several times (a different video each time). 4. Eventually, you get the described effect. Sometimes the first video does it, other times I need to try a dozen times before it happens. 5. Stopping the video and going back to search results stops the video and the main audio but the "echo" keeps playing until I exit all the way to the main screen. 6. Repeating the same search and going straight to play the video that seemingly triggered the bug does not trigger it again. The video plays fine this time.
