I know both media players are not on the same playing field(NMT vs basic media player) but since the price are not too far, I decided to make a comparison of both units. Having both units, here are the observations I got when comparing both units.
PQ - in my eyes, I haven't noticed any difference. I connected them to both plasma(full HD, HD ready, edtv) and lcd(HD ready).
AQ - no difference. Connected both to an AVR
Initial Loading time - WDTV has a shorter loading time than the m34a
Remote - egreat is bigger with more buttons to access the features of the player. It is also more responsive than the WD.
Features - this is where i felt the m34a is worth the upgrade
1. Plays the following files I tried (avi, divx, iso, mp4, mkv, m2ts, bluray rip, mp3, FLAC). Using the remote of a 31b, you can even browse thru the menu of dvd iso's. WDTV has problems playing large 1080p mkvs, bluray rips and iso's properly.
2. You can search a movie by percentage, ff or rew, go to a specific time. WDTV can only fast forward or rewind so you'll have to wait if you want to go or check the end part of the movie.
3. Most mkv files show black bars on top and bottom of the screen when using WDTV. On the egreat, you can watch using the whole screen.
4. You can copy, move, and delete files on your hard drive or from one hard drive to another hard drive connected to the other usb port using the egreat. WDTV can't manage files
5. Connections - egreat can send up to 1080p via component out. This is attractive for those people with HD tvs without hdmi connections . Aside from the hdmi, WDTV has composite out which can only send 480p(?)
6. Egreat has a power switch at the back. When it shuts down, the hard drive also powers off, unlike in the WD, when it is off, there is still power going to the external drive. Using the remote of the 31b, you can put the unit on standby.
7. Out of the box, it was easy to stream movies to this unit when connected to the router. You can easily see files on your shared folder and access them. No need for external hard drive if you don't have one at the moment.
8. Browsing experience for movie or music files is more "fun" when yamj or movie jukeboxes are installed for the egreat to access. On WDTV, only a small cover art is seen.
9. DTS downmix for egreat - self explanatory. I really have no use for this as i enjoy the experience of surround sound. I will probably use this when travelling or going to a place that has a tv but no surround system.
I think the extra cash spent on the egreat is worth it for those who are debating on which unit to buy. But if you have an avr and simply just want to watch a movie, the WD is a great player. Another plus for the wdtv is that it has a linux system and a lot of followers who build custom firmwares for added options and features. You can install a custom firmware and add a usb to lan connector to connect the unit to the network.
When it comes to portability, I still prefer the units which can accomodate internal HDDs. Less gadgets to carry, less wires and one power source.
