Problem is this:
Happens often when change channels.

Here is memproof debug:
see 2 Access violations and then application is terminated.

I downloaded old version ProgDVB 4.62.6 (full install), this version works fine.

BTW, there is also another AV in progdvbengine.dll (At the start of application) This doesn't force application to close, but anyway log:
-Edit-

My system: WinXP pro, Asus A7n8x, 512mb, Radeon 9600pro, Skystar 2. All drivers (Skystar, radeon, motherboard, ..) are updated to latest.

I have tried latest .net version (5.08.02). I get this same error, but it doesn't happen so often.

Exception happens in Windows file quartz.dll (as seen in log)

Hi , as discussed serveral times in this and the old forum...choose other Renderer in Progdvb ...and the Problem is gone
