I was having the same problem with a couple of videos. However, when I tried them on my home rig I still had excessive buffering. Most videos play without a hitch for me.
It only happens on some videos. My point is that the videos that had buffering issues on my tablet had issues on my home rig, which is MUCH more powerful (quad core, 8 GB ram), so I can't blame it on the tablet.
All the video's I stream on the a500 buffer, how can I fix this? Realy annoying! I was hoping that the nvidia software would be as smooth as my PC, flawless. Any ideas?
Same problem with youtube. Run 5 min and buffer and run 5 min and buffer .... It is okay with netflix so I think it is caused by youtube. Factory reset????
