Guest: XP SP3
The issue is that that whenever video decompression is needed (Windows Media Player with/without k-lite, TV-Tunner ...) nothing is shown up, just a blank window within the player. Also if I enable 3D Acceleration and test Direct3D in dxdiag it pops up an error : "Test failed at step 8 (Creating 3D Device): HRESULT = 0x8007000e (Out of memory)". I click Ok and then the rest of the test seems to work fine, but no 3D application works, showing "Direct3D Initialization Error".
DXDiag result :
DirectDraw test results: All tests were successful.
Direct3D 7 test results: Failure at step 8 (Creating 3D Device): HRESULT = 0x8007000e (Out of memory)
Direct3D 8 test results: All tests were successful.
Direct3D 9 test results: All tests were successful.
P.S.: Is video decompression done by GPU or CPU, I mean video codec file is loaded into memory and the complex functions are executed by CPU on the video file, right ?
edit: and i forgot, if i use VLCplayer which has it's own build-in codecs works fine .. and i suppose the answer for the upper question is GPU ..
