Thank you very much for your advises. I've installed wmp10 and MS Office 2007 into the clean wineprefix. However, sometimes PowerPoint hangs up during video play. It happens not every time. Terminal output during hang up: err:ntdll:RtlpWaitForCriticalSection section 0x894a9e0 "videorenderer.c: VideoRendererImpl.csFilter" wait timed out in thread 0035, blocked by 0069, retrying (60 sec) fixme:advapi:RegisterEventSourceW ((null),L"Microsoft Office 12 Sessions"): stub fixme:advapi:ReportEventW (0xcafe4242,0x0001,0x0000,0x00001b59,(nil),0x0006,0x00000000,0x339a84,(nil)): stub err:eventlog:ReportEventW L"3" err:eventlog:ReportEventW L"Microsoft Office PowerPoint" err:eventlog:ReportEventW L"12.0.6500.5000" err:eventlog:ReportEventW L"12.0.6425.1000" err:eventlog:ReportEventW L"99" err:eventlog:ReportEventW L"0" fixme:advapi:DeregisterEventSource (0xcafe4242) stub fixme:mscoree:GetVersionFromProcess (0xffffffff, 0x3380a8, 30, (nil)): stub fixme:heap:HeapSetInformation 0x110000 1 (nil) 0 fixme:imm:ImmDisableIME (-1): stub fixme:heap:HeapSetInformation 0x110000 1 (nil) 0 fixme:advapi:RegisterEventSourceW ((null),L"Microsoft Office 12 Diagnostics"): stub fixme:advapi:ReportEventW (0xcafe4242,0x0004,0x0000,0x000000c9,(nil),0x0000,0x00000000,0x504000,(nil)): stub fixme:advapi:DeregisterEventSource (0xcafe4242) stub fixme:advapi:OpenEventLogW ((null),L"Application") stub fixme:advapi:CloseEventLog (0xcafe4242) stub fixme:advapi:OpenEventLogW ((null),L"System") stub fixme:advapi:CloseEventLog (0xcafe4242) stub fixme:ole:CoInitializeSecurity ((nil),-1,(nil),(nil),0,3,(nil),0,(nil)) - stub! fixme:advapi:RegisterEventSourceW ((null),L"Microsoft Office 12 Diagnostics"): stub fixme:advapi:ReportEventW (0xcafe4242,0x0004,0x0000,0x000000d5,(nil),0x0000,0x00000000,0x504000,(nil)): stub fixme:advapi:DeregisterEventSource (0xcafe4242) stub fixme:advapi:OpenEventLogW ((null),L"Microsoft Office 12 Sessions") stub fixme:advapi:ReadEventLogW (0xcafe4242,0x00000009,0x00000000,0x8c0000,0x0007d000,0x33fd3c,0x33fd44) stub fixme:advapi:CloseEventLog (0xcafe4242) stub fixme:advapi:RegisterEventSourceW ((null),L"Microsoft Office 12 Diagnostics"): stub fixme:advapi:ReportEventW (0xcafe4242,0x0001,0x0000,0x00000140,(nil),0x0002,0x00000000,0x54e010,(nil)): stub err:eventlog:ReportEventW L"2kgl" err:eventlog:ReportEventW L"N/A" fixme:advapi:DeregisterEventSource (0xcafe4242) stub fixme:advapi:RegisterEventSourceW ((null),L"Microsoft Office 12 Diagnostics"): stub fixme:advapi:ReportEventW (0xcafe4242,0x0004,0x0000,0x000000cd,(nil),0x0000,0x00000000,0x504000,(nil)): stub fixme:advapi:DeregisterEventSource (0xcafe4242) stub fixme:advapi:RegisterEventSourceW ((null),L"Microsoft Office 12 Diagnostics"): stub fixme:advapi:ReportEventW (0xcafe4242,0x0004,0x0000,0x000003e7,(nil),0x0000,0x00000000,0x504000,(nil)): stub fixme:advapi:DeregisterEventSource (0xcafe4242) stub fixme:process:GetLogicalProcessorInformation ((nil),0x33fd80): stub fixme:netapi32:NetGetJoinInformation Semi-stub (null) 0x33fd7c 0x33fd70 wine: Critical section 0894a9e0 wait failed at address 0x7bc35fd3 (thread 0035), starting debugger...
