VLC used to hiccup at the start of every FLAC file I played. In both the Linux version and the Windows version on different machines. Several updates and it eventually got fixed but until then I used Media Player Classic. http://mpc-hc.sourceforge.net/ Or just for audio, Foobar: http://www.foobar2000.org/ Windows Media Player pretended not to even know the FLAC codec existed so I never had use for it. VLC amazed me by playing RAR'd up DVD(VOB) movies before they even finished downloading. Public Domain movies of course. The only thing you may want to watch if you install VLC is that they may try to slip in some useless(to me) toolbar, change your search engine or whatever. Just uncheck the box unless you want it. Actually, I had forgotten MPC until I started writing this so I installed it. To its credit, it didn't try to slip anything else into the install, which I like.

First I did a restore to remove two updates the evening of September 7, 8:36/8:38. The restore appeared to be successful, but the problem continues. So I restored back about one week and the restore terminated in "...did not complete successfully... system files and settings not changed" It went on to suggest I "temporarily disable anti-virus software" I couldn't find any way to disable Avira AntiVirus. But, I decided to try to view a picture form the desk-top, it worked this time, so I tried a video clip and it too now works. These were the two problems I noted ... go figure. Given I have removed several Microsoft updates, should I now go back to Microsoft and ask for a "Check of Updates"?

It's not on a site. The video was taken with the computerized microscope named Digital Blue. (It's a "toy" scope for kids but big kids like to play, too.) The files played on the original computer when I used the Digital Blue software. I exported the files from the Digital Blue folder then, once exported, copied to my thunb drive so that I could transfer to my computer. As I said, they won't play on my computers (both Vista) even though they both play avi files from other sources. I also tried to convert to another format via zamzar but received error message unable to convert. (Sorry, I don't recall precise wording. Could try again if it's important.)
