Weather it was fixed with the last firmware or not, i'm not sure, i got mine already at the latest... however, it only states this 8mbit limit to MPEG1 and MPEG2... For WMV and Mpeg4/AVI it dosent state anything, but both dont have as high bitrate as Mpeg1/2 anyway, but my high bitrate Mpeg2 TS files played fine, Except The unit cannot handle bad 3:2 Pulldown flags, eg... going from Film to Video mode. Its quite odd, but VERY common it seems with mpeg2 TS streams. I Endedup Converting those to Xvid Mpeg4 via AviSynth with the decomb filter, Runs smooth, Except over wireless. Only issue with that is that it takes me like 10 hours to recode a damn mpeg2 TS with AC3 to Xvid... but at leats they're a little smaller files
If you expect to run wireless HD, its a joke, soon as a high bit rate scene comes up, it lags big time... skip skip skip... Strangely it also speeds up the video, LOL, then slows back down in a lower bitrate scene. Quite ODD considering 54mbit should be quite quick... and i am 30 feet from the router, in line of sight too.
Also, For WMV HD, its Pointless, You'll have to Recode them all if you plan on having 5.1 Audio, Since it dosent support WMA 9 Pro Encoded Audio. Unless you have a A/V received that will decode it. i beleive it sends it Via Coaxial to the Receiver to Decode like AC3.
IMO, I would hold off and read reviews of players first, or you'll just end up being un-happy like me, hehe. First it was the DHCP, Then HDMI stuck at 480p (using component) then HD not being smooth over wireless.... BAD BAD Dlink
