My setup:


I am currently wirelessly streaming BR rip movies from my PC tower to a PS3. I have a gigabit connection from the PC to the router (D-Link DIR-825) which is broadcasting (5Ghz 'N') to a D-Link DAP-1522 bridge. Gigabit connection from the bridge to the PS3. The router is reporting a 70-75% connection with 240mbps, although I am realistic and don't expect that.


I had been ripping and compressing my BR movies to 4-8GB. I had never noticed any trouble with these because my network can easily handle the additional traffic if it had been doubling or tripling these. I recently purchased a 2TB HDD and decided to just rip and not compress a few of my favorites. So now instead of a 3-10Mbps stream I have 15-45Mbps streams. I am ripping them straight to an .m2ts container (AVC/AC3) when the original video codec is AVC and converting to .mp4 (AVC/AAC) with Ripbot if the original codec is VC-1. Neither container makes a difference.


What's happening is that when I stream these uncompressed BRs, the picture and audio stutter and jump (indicating a bit-starved network connection). When I check the bitrate reported by the PS3, it is showing 80-150Mbps. I have run these video files through Bitrate Viewer just to be sure, and they are all running at normal bitrates, i.e.

For 802.11N, the effective transfer rate, I guess is around 40-50 mbit/sec. Effective rate = actual bandwidth available, when you have 5 bars on the meter. Call it overhead or whatever but the 240 mbit advertised of 802.11n is bogus.

2 Important things You need to check:


1. Use only WPA2 Encryption


2. On Your router settings Change Channel Bandwidth from 20MHz to 40MHz (no wireless G,B, A devices can connect to your wifi-N router when you do this)


These should allow your network to operate as a true wireless N network and improve your wireless transfer throughputs...

I appreciate the feedback guys, but my available bandwidth is not the issue. My network is literally, somehow, increasing the bitrate on my streamed video files to a point that only a wired gigabit connection would be able to carry it.


If I reboot the PC and router, the first BR rip that I playback after the reboot(s) will be fine and the reported bitrates will be normal (15-45mbps). Playing back any movie after that results in the triple-bitrate effect where a normal BR rip is now reporting 80-200mbps and congesting the network, including the same movie that was just played normally.


Thanks for the feedback, though.
