Can't see video files on memory card file system

This message appears if data on the hard disk / internal memory / memory card of the camcorder is handled directly with the computer. When you handle data of the camcorder, use the supplied software, PMB.

If you directly handle files or folders of the camcorder from the computer, image files may be damaged or not be played back. Return the files or folders to the condition before handling, or format the recording media with the camcorder.

* If you format the recording media, all movies and still images including protected ones will be deleted.

* Sony will not accept responsibility for any results caused by handling data on the recording media from the computer.

This is the same to the images in the camera, if you have to do something with the images in your camera by PC, you won't playback it too.

You can recover deleted files with asoftech data recovery software. get the software from link below

card (up to 8GB) needs to be inserted in order to use the video mode normally.

When the icon appears on the top left corner of the LCD screen this indicates that you are in Video
mode.

1. Prepare the object or subject you wish to record.
2. Press the Shutter button to begin shooting the video.
3. The elapse time will appear on the top right of the LCD screen and the icon will flash on the

Alternatively, you can insert a SD memory card to expand the memory to record longer videos.
3. The LED will light up when the light condition is not good.

how did you transfer the video from the card to your PC?

did you connect the camcorder to your PC or did you use a memory card reader?

if you can play the audio then what you need is the right video codec for the unit
try searching for video codecs through search engines

make sure that the software that you are using to play the video plays the file format of your video,

try using roxio, then connect the camcorder to your computer via USB, make sure that the drivers are installed, play the video through your camcorder then use roxio to capture it real time instead of the usual "copy-paste"

In explorer - Under my computer/ devices - you will either have a list or details of files - the details under type will give you information of the file format - i.e videos may show as wmp, avi, etc

You must use the unit to play back. You are supposed to connect directly to television or other type of monitor. I do beleive you might need a password or something to view recordings. I am not sure but i do beleive you cannot remove hard drive and connect to a pc to view files they have to be run through the units software. I hope this helps.

Try uploading the files to you computer from the camera/
try the stick in another reader
A camera, a card reader on a computer or a processing station

i have the same problem. you have to play them back on divx player. i am trying to figure out if you can change the file from avi to jpg file that way it can be played back on any media player.

try quick time software for play back. Tell me what file extention your video files shows.
