I need to half take back what I advised earlier because I've read your requirement properly.
Video that has been viewed using WMP may either be on your PC as MPG files (or AVI) or MIGHT have been streamed down from a web link. These latter files MIGHT be present in your Temporary Internet Files folder with an AVI or MPG (or WMV) file type. These files can be copied to a permanent folder and processed.
Quicktime files have the file extension MOV and you MIGHT find them in the above mentioned folder if you have viewed the files online.
In that case you've captured what you want and don't need to process the files any further.
So forget the Nero thing; I use that to reprocess files and I've got other software too that converts video types.
Does that work with streaming? You're in WMP - right? So what do you set to save the streamed file? /QUOTE] i don't think this works ,usually you need software to capture streaming video .this one for firefox .will capture video from youtube and other sites http://download-streaming-video.qarchive.org/
if you put the mouse over the video file and right click it gives you the option to open with a secific program , so click on choose program and pick the one you prefer and tick the change all box at the bottom.
I hope this helps
I use ads tech dvdexpresdx2 for all my video capture needs , and i recommend it highly.
Also as a bonus avi to mpg converter built into it.
I tried a video capture by pinnacle and it slowed my pc down entirely to the point of it taking 1 minute to open a web page & also the software came on 3 discs.
