I extracted the VirtualDubMod files to a directory, then extracted the bug fix files from VirtualDubMod_1_5_10_1_b2389.zip. crashinfo: VirtualDub crash report -- build 2389 (release) -------------------------------------- Disassembly: 004b50a0: 8bec mov ebp, esp 004b50a2: 56 push esi 004b50a3: ff7508 push dword ptr [ebp+08] 004b50a6: 8bf1 mov esi, ecx 004b50a8: e810580c00 call strdup (0057a8bd) 004b50ad: 85c0 test eax, eax 004b50af: 59 pop ecx 004b50b0: 894608 mov [esi+08], eax 004b50b3: 7516 jnz InputFilenameNode::InputFilenameNode+2c (004b50cb) 004b50b5: 8d4d08 lea ecx, [ebp+08] 004b50b8: e860370700 call MyMemoryError::MyMemoryError (0052881d) 004b50bd: 6800d45b00 push 005bd400 004b50c2: 8d4508 lea eax, [ebp+08] 004b50c5: 50 push eax 004b50c6: e8201f0b00 call _CxxThrowException@8 (00566feb) 004b50cb: 8bc6 mov eax, esi 004b50cd: 5e pop esi 004b50ce: 5d pop ebp 004b50cf: c20400 ret 0004 004b50d2: ff7108 push dword ptr [ecx+08] 004b50d5: e8f4140b00 call free (005665ce) 004b50da: 59 pop ecx 004b50db: c3 ret 004b50dc: 55 push ebp 004b50dd: 8bec mov ebp, esp 004b50df: 53 push ebx 004b50e0: 56 push esi 004b50e1: be76696473 mov esi, 73646976 004b50e6: 397508 cmp [ebp+08], esi 004b50e9: 57 push edi 004b50ea: 8b7d0c mov edi, [ebp+0c] 004b50ed: 750a jnz InputFile::GetSource+1d (004b50f9) 004b50ef: 85ff test edi, edi 004b50f1: 7505 jnz InputFile::GetSource+1c (004b50f8) 004b50f3: 8b4118 mov eax, [ecx+18] 004b50f6: eb64 jmp InputFile::GetSource+80 (004b515c) 004b50f8: 4f dec edi 004b50f9: 8b410c mov eax, [ecx+0c] 004b50fc: 8b4910 mov ecx, [ecx+10] 004b50ff: 3bc1 cmp eax, ecx 004b5101: 7457 jz InputFile::GetSource+7e (004b515a) 004b5103: ba000f0000 mov edx, 00000f00 004b5108: 397508 cmp [ebp+08], esi 004b510b: 7430 jz InputFile::GetSource+61 (004b513d) 004b510d: 817d0861756473 cmp dword ptr [ebp+08], 73647561 004b5114: 7418 jz InputFile::GetSource+52 (004b512e) 004b5116: 817d0874787473 cmp dword ptr [ebp+08], 73747874 004b511d: 7534 jnz InputFile::GetSource+77 (004b5153) 004b511f: 8b18 mov ebx, [eax] 004b5121: 8b5b10 mov ebx, [ebx+10] 004b5124: 23da and ebx, edx 004b5126: 81fb00030000 cmp ebx, 00000300 004b512c: eb1c jmp InputFile::GetSource+6e (004b514a) 004b512e: 8b18 mov ebx, [eax] 004b5130: 8b5b10 mov ebx, [ebx+10] <-- FAULT 004b5133: 23da and ebx, edx 004b5135: 81fb00020000 cmp ebx, 00000200 004b513b: eb0d jmp InputFile::GetSource+6e (004b514a) 004b513d: 8b18 mov ebx, [eax] 004b513f: 8b5b10 mov ebx, [ebx+10] 004b5142: 23da and ebx, edx 004b5144: 81fb00010000 cmp ebx, 00000100 004b514a: 7507 jnz InputFile::GetSource+77 (004b5153) 004b514c: 8bdf mov ebx, edi 004b514e: 4f dec edi 004b514f: 85db test ebx, ebx 004b5151: 7410 jz InputFile::GetSource+87 (004b5163) 004b5153: 83c004 add eax, 04 004b5156: 3bc1 cmp eax, ecx 004b5158: 75ae jnz InputFile::GetSource+2c (004b5108) 004b515a: 33c0 xor eax, eax 004b515c: 5f pop edi 004b515d: 5e pop esi 004b515e: 5b pop ebx 004b515f: 5d pop ebp 004b5160: c20800 ret 0008 004b5163: 8b00 mov eax, [eax] 004b5165: ebf5 jmp InputFile::GetSource+80 (004b515c) 004b5167: 56 push esi 004b5168: 8b742408 mov esi, [esp+08] 004b516c: 85f6 test esi, esi 004b516e: 7505 jnz InputFile::GetSource+0e (004b5175) 004b5170: 8b4118 mov eax, [ecx+18] 004b5173: eb25 jmp InputFile::GetSource+33 (004b519a) 004b5175: 8b510c mov edx, [ecx+0c] 004b5178: 85d2 test edx, edx 004b517a: 7504 jnz InputFile::GetSource+19 (004b5180) 004b517c: 33c0 xor eax, eax 004b517e: eb08 jmp InputFile::GetSource+21 (004b5188) 004b5180: 8b4110 mov eax, [ecx+10] 004b5183: 2bc2 sub eax, edx 004b5185: c1f802 sar eax, 02 004b5188: 8d56ff lea edx, [esi-01] 004b518b: 3bd0 cmp edx, eax 004b518d: 7309 jnc InputFile::GetSource+31 (004b5198) 004b518f: 8b410c mov eax, [ecx+0c] 004b5192: 8b44b0fc mov eax, [eax+esi*4-04] 004b5196: eb02 jmp InputFile::GetSource+33 (004b519a) 004b5198: 33c0 xor eax, eax 004b519a: 5e pop esi 004b519b: c20400 ret 0004 004b519e: b8 db b8 004b519f: 92 xchg eax, edx Windows 5.1 (Windows XP build 2600) [Service Pack 1] EAX = 00c4fdc8 EBX = 00000000 ECX = 00c4fdcc EDX = 00000f00 EBP = 0012f7ac DS:ESI = 0023:73646976 ES:EDI = 0023:00000000 SS:ESP = 0023:0012f7a0 CS:EIP = 001b:004b5130 FS = 003b GS = 0000 EFLAGS = 00010246 FPUCW = ffff027f FPUTW = ffffffff MM0 = 0000000000000000 MM1 = 0000000000000000 MM2 = 0000040000000000 MM3 = 0000000000000000 MM4 = 0000000000210000 MM5 = 2000000420000004 MM6 = 00f800f800f800f8 MM7 = 0000fc000000f800 Crash reason: Access Violation Crash context: An out-of-bounds memory access (access violation) occurred in module 'VirtualDubMod'.

| The File Information seems to work fine with a system MPEG-2. The problem seems to occur on elementary video MPEG-2 streams with no audio. Regardless of the size of the MPEG file. I have also installed the fixes from build 2424 - same error. |
