I have a N800 and have been using the r13 build for a while now with no problems. However, upon upgrading to r15, my videos no longer play. It appears to be an audio problem, though I'm not sure. Here's the output from the logfile: ********************************************* And here's the log from r13 using the same video: *********************************** The video (an episode of arrested development) was first ripped from the DVD, then converted via ffmpeg. I have had no problems viewing these using r13, but but r15 definitely seems to have a problem. I'm pretty sure I tried r14 too, with the same results as r14. Hope this helps.... -dave
