I have trouble playing incomplete .avi files and files downloaded from video.google.com. Can you help?
Enable the internal AVI splitter in Media Player Classic, which is better able to handle incomplete files than the default AVI source filter that is part of Windows. To access these options: start Media Player Classic and click on View in the top menu, then click on Options… (the last item) and then click on Internal Filters, there you can find the option under Source Filters. For other players you need to install Gabest AVI splitter.
