I recently bought a WD tv live, but I have problems while playing mkv files.
My system:
iMac 27", 16GB RAM, i7, 256GB SSD, 2TB HDD with several mkv stored in it.
Router Netgear wi-fi WNDR4500
The signal is full both on Mac & wd tv. The router can support 5MB/s transfer speed between devices, tested with iMac → MB Air connection. So the router can fully support HD transmission: I can smoothly play a mkv (even >40GB) on my MB Air reading it through wifi connection.
Yesterday I was watching a 16GB mkv on my TV and it played smoothly for 25 minutes, but suddenly it began to reduce the frame-rate, and the film became unwatchable because every 2 seconds, it stopped. I tried to restart the film, even from the beginning, but the problem was still there: every second there where dropped frames.
Can anyone help me?
An “Average” of 5MB/sec is HARDLY sufficient for streaming HD media.
HD media requires up to 40 megabits per second – UNINTERUPTED.
Your MacBook can probably do better because it buffers so much more media.
The film I was watching has this specs, as you can see the bitrate is around 15 megabits per second:

Agreed… but that’s an overal average… You’d need to know what the peak bitrate is.
