I recently purchased a Acer Aspire Revo AR3610-U9022 Intel Atom 330(1.60GHz) 2GB DDR2 160GB NVIDIA ION graphics Windows 7 Home Premium 64-bit. It is intended to be a Media Player PC in Master B.R. Main PC down stairs is Intel I5 Windows 7 64 bit. It by the way plays all HD movies fine in Media Center. After doing all the stuff that is recommended, remove bloat, update drivers
, turn off unneeded services and startup processes etc etc, I have not been totally succesful with playing HD 1080P files, (mainly ripped blu ray to MKV, all using same rip software). I have loaded the latest shark007 32 bit and 64 bit packs. Have selected recommended settings in both 64 bit and 32 bit Shark. Using Windows 7 Media Center, streamed or from Acer's hard drive, all 1080p content is jittery or totally unwatchable. 720P content playes fine. Checked cpu resources for 1080p attempts and it was averaging around 45% on semi watchable movies. Did not check cpu on movies that were totally unwatchable. I also tried the latest XBMC player build that has DXVA support. With that support turned on, half of the Blue ray rips (in MKV with same file size as original blue ray files) played excellently. The other half that I tried had random moisly green pixles on bottom half of screen. CPU usage was averaging around 10%. I tried Boxxee, which says it has gpu accelaration. Two movies that would not work in XBMC worked, others did not. CPU usage percent was low also. Was also thinking of trying Meida Center classic. Ultimately, it looks like if I could get DXVA to work in windosw meida center, it seems these should all play perfectly in win 7 media center. Sorry for the long post but more details might help some one to help me. How can I get these HD movies to play flawlessly in Media Center, XBMC or in some other player. Thanks for any assistance.
