in visual studio press Ctrl+Alt+E. select <Common Language Runtime Exception>.
and run the sample code, when you click Next button. MediaPlayer1.Stop() will throw:
InvalidComObjectException : COM object that has been separated from its underlying RCW can not be used

I suspect that: you release the resource have a problem. and that would let the "Unable to perform first rendering." or the crash happening. please hurry. I can't wait all day for one question.

I hope that you can have more positive and I do not want to bother you, because I am very sorry to give you always find BUG. I'm so tired.

just like I said before, full screen , it's really very easy to implement.
I just try videgrabber ,very unfortunate. looks like it's not support multiple audio stream.

I think you can use visioforge product. because It is indeed a powerful, if you need some it has no function, you can give them suggestions. (but not the full screen)

Are you C# developer? or....?

Full screen is easy, just conver screen using your window and cover your form using control. We can made a sample demo if required.

My team already made software with xx graber like this :

http://www.mediafire.com/?oo1iw3wsgqzyu5u

pass winrar : xdmultimedia

It's posiblle also with VisioForge ?
1. Load external winamp plugins
2. play mkv with auto sub tittle
3. Dual view on monitor 1 and monitor 2

We still evaluation your product to consider change old SDK if posiblle.
Sometimes we dreaming make karaoke software like XBMC, we have budget $1000 - $1500

Why you want to use mkv?
I recommend you to use their MP4 H264 / AAC Directshow SDK 7.0(H264) or Video Encryption SDK 7.0(also H264, and Copy-protected)

Sure. But you also need warning you customer, copy media file is very easy, but losing is big. haha... you choice. another reason is H246 media file is small, can save a lot space.

Some feature you want. I already implement it before use C#, and some problem is already solved. so maybe you don't worry a lot. So you very lucky.

1.Winamp maybe visioforge will make it for you if you want.
2.Maybe you already see the Demo.
3.I need the Function too, and I already finish it.
4.about the Blueray film , I don't know...you customer cpu must be strong. haha...auto sub title maybe you need request.
5.this is I already doing , but .... I make it myself. maybe you need make it yourself.
6.this is not a big problem I think, you can do it.

So those problem really not a problem, what you need to worry is : SDK is stable? Would not crash? How to solve? .... Etc.

Now I need to play a lot of files, it will occasionally crash when I'm play Next file, so this is the most terrible problem.

Unfortunately, if you are using C#, then exchange more convenient.
