Hello 1) I am using windows XP and my system detailed configuration is at www.spunge.org/~valtea/report.htm and I have pinnacle Studio 8 installed in my system. I use it for video editting. I have Pinnacle Hollywood FX 5 Pro-Plus installed in my system which i used it for transistions in Pinnacle Studio 8. Lately i have experienced a new problem. My studio hangs very often and i get error message. Specially when i try to apply for transistion this error happens. Is it due to my display adapter driver or something? because in the error messege that i get it contains sisgl.dll as a ModName. Studio program file has encountered a problem and needs to close. We are sorry for the inconvenience. Error Signature AppName : studio.exe AppVer: 126.96.36.199 ModName: sisgl.dll ModVer: 188.8.131.5211 Offset: 007ca7c Detaile of the error messege is here at www.spunge.org/~valtea/error.txt 2) Also even when my studio was working properly, some of the transistions were not rendered correctly. 3)And moreover sometimes the video file becomes blank (Green) in the studio Timeline. And exporting those blank green files does not help as it produces another green blank file. However the files which appear green (blank) in Studio are not so when viewed in Media Player or other players. Is this because of poor quality video file? Please help me Thanking you.
