I run Twonky server on my Ubuntu server at home. I tried streaming my AVI files whether using the DLNA client or the available Twonky client and all I get is video but never audio. Couldn't seem to understand why (something about codecs and MPEG type video...blah, blah), but via google, this seems to be a known issue unless the file was sync'd/converted to the local device...which seems defeats the point of streaming.
Anyway, all of my searches pointed me towards RockPlayer Lite (I didn't find a pay version), but that wasn't enough since it's just a player. So I found UPnPlay which can connect and browse your DLNA sources AND requires you to select an external player like RockPlayer.
With the combination of these two I get true video streaming to my device.
Regular audio files from my server never suffered any issues when streamed using the DLNA client. Twonky client blew chunks and has since been uninstalled.
