Thanks, but I have plenty of .mp4 files to use, most of the rest are .flv. If it were necessary to convert to .avi, I would pass, because I've had a lot of them that required being repaired for them to be able to play. I like files that are more reliable than that.
Regarding your comment about WLMM, it appears that you think that I meant that the names were in the film itself...not so. VLC extracts the name/title from the properties detail field and displays it momentarily as mentioned. Therefore clipping the file would not help, unless there was something somewhere otherwise invisible that that VLC used as part of the name field of the details tab.
Often the download source is placed there, with or without the film title and produces a long line on screen that is nearly indecipherable in the short time it appears, but is correctable by the means that I described. However, all data, both wanted and unwanted is clearly visible on the tab, and correctable via keyboard, as with any line of text normally is.
