hi, i tested dvdshrink http://www.dvdshrink.org/ and with the following dlls (win98 ones, just copied them in my wine/windows/system directory, I don?t if you need them all!) it runs nearly perfekt! advapi32.dll comctl32.dll ddraw.dll gdi32.dll kernel32.dll mfc42.dll msvcrt.dll ole32.dll rpcrt4.dll shell32.dll shlwapi.dll user32.dll But if i activate reencoding a warning message comes up, this is the debug message it gaves out: "wine: main.c:572: DDRAW_width_bpp_to_pitch: Assertion `bpp != 0' failed." the rest of the programm works well, but this error causes that you cant choose the audio tracks of the source dvd, so all are activated! what can i do? mfg floyd
