I've been playing with the ouya's for awhile now and have had the problem that a few people encountered with stuttering through ethernet or the funny machine gun like sounds that would crop up every now and then. some people have said the stuttering starts 10 minutes in or 20 minutes in or half way through a movie etc. eventually the movie or video would freeze up. I seemed to experience all these symptoms at one time or another. at first i thought it was maybe a running out of memory or cache issue but I always saw quite a bit of buffer built up ahead of the stream, so i knew my streaming speed was OK. I've done alot of reading and the info i've found has been few and far between but I did find a couple things that seem to have helped clean up this issue for me. my ouya's now seem to run flawless with everything I've thrown at them. and I did some testing on files that would stutter, then change settings and see the results. changing the settings below made all the difference for me.
just want to share what i've found in hoping it helps others if there experiencing the same problems. thxs goes to those that have posted these settings in different threads that seemed to help for them. (tuxen being one of them)
should start by mentioning I'm running the second to last ouya store xbmc version... the one that doesn't have ac3 or dts disabled....
1) I was using cachemembuffer = 0 advanced settings. I found that changing over to tuxens advanced settings xml (xbmchub maintenance, tweaks) seemed to work better. it still showed buffer building ahead but wouldn't build up as far ahead as the 0 setting xml... it's been mentioned by some that running any cachemembuffer size may not be necessary. I can't argue but tuxens version seems to be doing well for me so I'm going to stick to it for now.
2) under settings, video, file lists, I disabled the setting "extract thumbnails and video information"
3)under settings, video, playback
render method auto detect
allow hardware acceleration enabled
adjust display refresh rate to match video off (disabled)
pause during refresh off (disabled)
rate change off
synch playback to display enabled
a/v synch method video clock (resample audio)
allowed error in aspect ratio to minimize black bars none
display 4:3 video as normal
activate teletext disabled (not sure if this makes a difference)
scale teletext to 4:3 disabled (not sure if this makes a difference)
some people also disable rss feeds in settings appearance, I believe. but I found this doesn't make a difference for me and I prefer to leave that setting enabled as it's a quick visual way to see that you are connected to the internet when starting up....
you can also go into the ouya section, advanced, apps, xbmc, and scroll down and click clear cache....
with these settings I am getting video's that were previously stuttering to play butter smooth with no stuttering or machine gun like sounds through playing multiple movies in succession as long as the bitrate of the video isn't so much that streaming can't keep up.
hope this might help some peeps,
gotta say these ouya's kick ass!
have a good one,
