We drag all our crap into VS and start cutting within the system. Most amateur users, like myself, skip this step. So VS doesn't replace these tools, it works in conjunction with them. These tools are very specific and are great for preliminary rough cuts to delete a lot of garbage video off your hard drive. Another program to try is I have not used it but apparently it is specific to WMV and can cut the video lossless.

This may be true or the file may need to be 'tweaked' but still fits the developer's definition of 'lossless.' I honestly don't know, but like Video Studio it passes the MediaInfo test. You may convert it from the menu for a better preview with audio.' So what does that exactly mean? WMV is not native to the program but it will be lossless in the end - trust me. The final export will however be lossless with audio.

Preview may have no audio or low quality. As for LosslessCut, when you drop a WMV file into it the following message appears:

As for WMV, as mentioned by Djard007, I don't think Avidemux can cut and save it in its native format. As for the other 'lossless' editors we can only take them at their word. As Djard007 has indicated MediaInfo may not specifically determine video quality but it is a good quick check to determine if the new file has the same attributes to the source or has materially changed. Is it purely 'lossless' or does it do a little bit of rendering, I'm not sure. Trevor, that was my understanding as well 'saved trimmed video' creates a new file with the original video properties/attributes.
