I have not paid too much attention to this before but just today I noticed that TMPGEnc 2.521.58.169 tells me that my End Frame for this particular AVI is 195412 while VirtualDub 1.5.10 tells me the last frame is 156174. Is there a problem here or is this common and I've just not noticed the difference before?

AVICodec tells me this about this AVI:

File : 665 MB (665 MB), duration: 1:48:33, type: AVI, 1 audio stream(s), quality: 52 %
Video : 545 MB, 702 Kbps, 23.976 fps, 640*272 (2.21:1), DIV3 = DivX v3 MPEG-4 (Low-Motion), Supported
Audio : 120 MB, 155 Kbps, 44100 Hz, 2 channels, 0x55 = MPEG Layer-3, Supported

Any ideas about this?
