I don't usually post reviews, but I thought that this subject was worth mentioning in case anyone else is having problems with Windows Media Center (WMC) and Linksys Media Center Extenders (MCEs).
Here's the situation, I used to have a pair of Linksys MCEs that I used with my WMC computer; a DMA2100 and a DMA2200. (Although when I bought an Xbox 360 a few years ago, I configured it as an extender, and I gave the DMA2100 to my dad to use with his WMC computer.)
That being said, the Linksys MCEs never worked perfectly for me. They worked fine with DVR-MS, WTV, and WMV files, but for some reason they never worked well with MP4 files - which included my entire library of personal DVDs that I painstakingly ripped and stored in a Media Library on a NAS unit. However, I should mention that MP4 files played just fine on the WMC computer itself, just not on the Linksys MCEs.
I realize that all of the file types which I listed are just wrappers around the underlying media, so I was always perplexed as to why an MP4 file would never work with the fast-forward, skip, rewind, or pause buttons on my Linksys MCEs even though a WMV file would. What's more, most MP4 files would play for about a minute, then the playback would freeze/skip/etc. for a little bit, and then it would usually stabilize for the rest of the video. (Although sometimes the video would never come back and I had to stop the video or reset the MCE.)
I should point out that all of my devices are hard-wired to gigabit networking hardware, so throughput should never have been a problem. (In fact, running the networking tests from the Linksys MCEs always showed bandwidth off the scale.) I eventually decided that the DMA2200 would have to be limited to just playing back recorded TV, which made it a rather bad return on investment.
For the past few years I had thought that the problem was simply some sort of compatibility issue with Windows Media Center and MP4 files when using an MCE, but I never had any problems with my Xbox 360 when using it as an MCE. In fact, the Xbox works so well that I have disconnected my WMC computer from my TV and now I exclusively use the Xbox to control my WMC.
Seeing as how the Xbox was working so well, it finally dawned on me that the problem had to be something internal to the Linksys MCEs. With that in mind, I started shopping around for a second Xbox 360 to replace my remaining Linksys MCE, but first I decided to read some of the Ceton Echo reviews on Amazon.
Several of the reviewers specifically mentioned my exact scenario; they were using Linksys MCEs and they were having problems with the video freezing/skipping, and the Echo resolved the problem. With that in mind, I decided to give the Echo a try.
My Ceton Echo arrived a few days ago, and it was a breeze to set up. The footprint is much smaller than either the Linksys DMA2100 or DMA2200, and it's obviously a lot smaller than an Xbox 360. Another nice feature was that the Echo accepted commands from my existing Linksys remote; this was great for me because I had already configured my Linksys remote to control my TV, so I didn't have to change anything else in my setup if I didn't want to.
All of that being said, the most-important benefit after replacing my Linksys MCEs with the Ceton Echo is - no more skipping or freezing when playing MP4 files, and I can use the skip-forward, skip-backward, and pause buttons on the remote when I am viewing MP4 files. One small downside is that the fast-forward and reverse buttons do not seem to work with MP4 files, but I can live with that.
So in closing, if you're using a Linksys Media Center Extender and you're having issues with it, you might want to seriously consider replacing it with a Ceton Echo.
