Everything works... except mkv (stuttering)

I have looked at several posted solutions and configuration settings. I'm stumped.

I am currently using a CGD24G netgear wireless hi-speed cable router, a windows 7 PC (very fast gaming computer - i7 overclocked) with serviio installed, and a brand new Samsung UN40EH5300 TV.

I have tried this solution, and this solution, to no avail. Also done alot of trial and error with the settings. I am currently using the default config for profile "Samsung TV / player (C/D/E-series)."

What happens is with every other file, the video play is great - I can even fast forward and rewind to some extent. But with MKV the stream stutters and I get "loading..." every ten seconds or so. I just can't figure it out. Please halp! lol.

Update: I let a movie (Avatar.mkv) run for a little while through the stuttering. About 5 minutes in, the periods between "loading..." increase and It becomes somewhat watchable. But then about 20-30 minutes into it, I get disconnected with this message "device disconnected device:serviio." My router has "transmission speeds of up to 54Mbps." Are these problems because my router simply isn't fast enough?

The disconnects happen even if I am not watching an mkv file. Any ideas on all this?

I assume the mkv's are high-def movies, and you can expect stuttering of such content when streamed wirelessly. You should connect the TV and the Serviip PC/router with cables.

Yes, they are high-def mkv movies. The TV is too far away to connect with cables unfortunately (and it would look really bad stringing a cable over there).

Would a more powerful wireless modem solve the problem? Mine is 54 MB/S and doesn't have dual band. If I got a more powerful one with dual band, 300 MB/S+, and QoS/WMM do you think that would solve these problems? Or is a wire the only way? I'm willing to spend some decent cash on this if I have to.

I think there are adapters you can get to use your electrical wiring to connect your devices.

Either the adapters (if your electricity cabling is good), or try the wifi router (not sure if you can return it to the shop in case it wont help you).

I decided to just wire it along the baseboards. I got a 5e ethernet cable and it works much better. Also it saved me hundreds of dollars.

Thanks guys!
