  • Get a fixed image and audio while playing a movie in Windows Media Player, also get the message: "network is too busy to read the file to its original quality.

    Original title: Windows Media Player

    When I go to play a movie using windows MediaPlayer all I get is an imagwe again with audio and this message 'network is too busy to read the file to its original quality. Also, all my other media playing programs read the video but are rather "lag". I think the problem is that I already used a program to download torrents called 'BitTorent' and maybe this has used up all my bandwidth or processing speed? Not really sure but would really like it if I could still use WMP and I'm looking for resolution to my problem?

    Thank you

    Yesterday, I got no sound and video, today I have sound but no video.  What is happening with this?

    I updated my drivers and now the video does not work.  I use Windows Media Player c. 9.00.00.4510.  When I click on read the file, in the black bar at the bottom ready it flashes very fast "error downloading codec".  Before I updated the drivers, I got the video with no sound.  Where this codec disappeared to?   How can I get that back?

  • Cannot import files - said "cannot read the files.

    Hi all!  I just finished a session with my Nikon D610 and when I tried to import photos that Lightroom tells me that it is impossible to read the files.  It is the second time this has happened to me.  Finally, he just started a first time around, but not for a couple of weeks of work. I don't have that long this time.  Any suggestions? Thank you!

    The error message "Unable to read file" is pretty bad of foreground. What this really means is that Lightroom is unable to 'write' files.

    Check your Destination folder in the import dialog box. He must have all the read/write permissions and be on an internal or connected external hard drive and with enough space.

    I assume that your version of Lr is compatible with the D610.
