After opening either Video Editor or Video Converter, and importing an MTS file using Windows 7 Ultimate with Aero enabled, the application will crash the DWM repeatedly, until the application receives a "AVS Video Editor has stopped responding" windows dialog.

Event Viewer shows errors such as :

Hello,

Try disabling caching in AVS Video Editor>top menu Edit>Settings>Environment.

If it does not help, please specify your PC configuration - Operating System, CPU, Ram, Video Card, PC vendor.

Best regards.

If you change theme to Windows 7 basic (and disable DWM) then both applications work fine. I'll use this as a workaround for now.

Not sure why either application needs to do anything that should affect DWM though really (except for the screen capture).

Machine is a Thinkpad T420 with a sandy bridge i7, 8gb ram, intel hd 3000 graphics, and win7 ultimate.

Hello,

The issue might be connected with shortage of RAM.As themes in Windows 7 and DWM consume a lot of RAM.Besides normally MTS files are large ones so they also use RAM while importing into AVS Video Converter. All this factors cause the shortage of RAM.

I don't believe that to be the case Lex, if it were I would receive "out of memory" errors from windows, also I can see in task manager that the memory consumption is nowhere near the 8Gb limit.

The DWM crashes as soon as you attempt to convert or import the MTS file into the editor, and it repeatedly crashes this process. I suspect the video converter/editor has a memory leak and is writing to memory it doesn't own in the DWM process - which crashes that process.

There are many other processes in Windows which consume RAM also, so I would ask - why are they not crashing, and what exactly is the converter/editor doing that interferes with DWM and crashes it?

Without running procmon and other tools on the AVS programs I can't tell, and I don't have the time to do that right now, and to be honest - it's not really my responsibility to be fair.

Hello,

The intel hd 3000 graphics doesn't have discrete graphics memory. But it consumes the cach memory of processor as well as of RAM. While using DWM the graphic card increase the consumption of RAM.This scaled-up consuming causes clashes with multimedia product which in its turn also use a lot of RAM.

Best regards.

To: Lex


The fact that it uses processor cache time means nothing. All windows apps will do that.

DWM uses 100Mb of RAM - thats less than skype.

The consuming isn't "scaled up" at all, just because the graphics are inside the CPU.

There is nothing wrong with my "RAM consumption" here.

The symptoms of RAM shortage are not manifest anywhere during this issue at all.

The fact is that some code in either the product, or a dependency of the product, repeatedly crashes another windows process.

I have a workaround by disabling Aero, so i'll use that for now.

When I have time i'll profile your app through either depends or procmon, and i'll post you the results so you can try and reproduce.

Hello,

I'll be waiting for the results.

Best regards.
