天狼星加密视频怎么翻录
1、查找字符串找到004684EC mov eax, 00468A0C 播放授权不合法！004684FB mov eax, 00468A28 播放授权不正确！00468581 push 00468A44 yaomediakj1jf ；在这双击，找到头下硬件执行断点00468650 mov eax, 00468A5C 播放密码不正确00468675 push 00468A74 c:\china-drm\004686B4 push 00468A8C .ini00468765 mov eax, 00468A5C 播放密码不正确004687DD push 00468A9C yaomediakj2jf004688D8 mov eax, 00468A5C 播放密码不正确004688E9 mov edx, 00468AB4 ok0046893B mov edx, 00468AC0 000468B3F push 00468D8C yaomediakj3jf ；在这双击，找到头下硬件执行断点00468C4A mov edx, 00468DA4 000468CD1 mov edx, 00468DB0 c00468DBF mov eax, 00468DE8 确信要退出吗？00468E02 mov edx, 00468E1C ok
2、第一个断点0046830B 51 push ecx ; 以防退出下个硬件执行断点0046830C 53 push ebx0046830D 56 push esi0046830E 57 push edi第二个断点00468AD7 53 push ebx ; 在这F200468AD8 56 push esi00468AD9 57 push edi
3、下完这两个断点，F9运行，输入假码111111111111111111，18位，（如果是出现其它错误。把出错CALL，NOP掉，如果前两位是9d的话可能不会出错）确定，断下，F8单步向下走0046830B 51 push ecx ; 第一个断在这里。0046830C 53 push ebx0046830D 56 push esi0046830E 57 push edi0046830F 8BF0 mov esi, eax00468311 33C0 xor eax, eax00468313 55 push ebp00468314 68 DA894600 push 004689DA00468319 64:FF30 push dword ptr fs:[eax]0046831C 64:8920 mov dword ptr fs:[eax], esp0046831F 8D45 DC lea eax, dword ptr [ebp-24]00468322 E8 99C4F9FF call 004047C000468327 8D95 0CFEFFFF lea edx, dword ptr [ebp-1F4]0046832D 8B86 08030000 mov eax, dword ptr [esi+308]00468333 E8 0444FDFF call 0043C73C00468338 8B85 0CFEFFFF mov eax, dword ptr [ebp-1F4]0046833E 8D55 FC lea edx, dword ptr [ebp-4]00468341 E8 FE05FAFF call 0040894400468346 8D95 08FEFFFF lea edx, dword ptr [ebp-1F8]0046834C 8B45 FC mov eax, dword ptr [ebp-4]0046834F E8 A003FAFF call 004086F400468354 8B95 08FEFFFF mov edx, dword ptr [ebp-1F8]0046835A 8B45 FC mov eax, dword ptr [ebp-4]0046835D E8 6AC8F9FF call 00404BCC ；这个CALL是关键CALL，调用了好多次，看了下里面也没的改。00468362 0F84 99000000 je 00468401 ；这个JE如果不跳，就不管他(根据自己输入的假码，有时不跳但后面有出错的地方)，跳的话就NOP掉-------------
