‘Building font cache’: VLC Media Player doesn’t like AppData on a UNC path
I’ve known for a long time that Adobe Reader doesn’t play nicely with redirected AppData folders, but I really thought VLC was better than this.
Annoyingly, since version 1.1.0, VLC Media Player doesn’t like the user’s AppData directory being on a UNC path (i.e. starting with a \\). It wants a drive letter. If you do redirect AppData to a UNC path, you may well end up seeing this sodding annoying screen every time you play a video:
If you’re lucky, it will take “less than a few minutes” and the video will start playing immediately afterwards. If your experience is similar to mine, it will take longer than a Windows Service Pack install, and be followed with another inexplicable delay before the video eventually plays (assuming you haven’t gotten bored and given up by then).
The VLC team have been made aware of this, but it’s not yet fixed. For now, if you redirect user AppData to a UNC path, stick to version 1.0.5. This does make the procedure for using SAP announcements with IPTV (scroll to about 2/3 of the way down) a bit more tedious, but it’s that or nothing right now.
