I can't play a hi8 cassette recorded in another camera y my camera, what can i do?

Is the Canon UC9 a HI8 camera?? If not it wont play HI*.

Be sure you have rewound your cassette to the beginning before playing back your video. Also, be sure that the tape heads of your camcorder are clean.
Use head-cleaning tapes regularly to keep your camera in top shape.

Hi,

Based on the information you've provided, it seems that the issue is with the dirt in the Video Head of the Camcorder. You can try using new Hi8 tapes for recording the videos to check if they are playing back normally. If the audio is working normally in the Camcorder, then the issue is with the dirt on the video head. If the issue persists with all the tapes, then the video head can be cleaned using a dry Video Head Cleaner Cassette. You can purchase the cassette from the Sony Authorized dealers or from the local electronics store. Please make sure that the cleaning cassette is compatible with the Camcorder.
This should resolve the issue.

Thanks for using FixYa.

I have the exact same camera and same exact same problem. Any analog Video8 or Hi-8 camcorder or VCR will play these tapes.

By using the same cassettes as Hi8, many (NOT ALL) Digital8 (produced by Sony exclusively) camcorders are able to play analog Video8/Hi8 recordings, preserving compatibility with already recorded analog tapes.

you can connect Digital8 camcorders to your computer to download your movies for editing or Internet use.

As of 2008, Digital8 camcorders have been removed from the equipment offered by Sony.

To the best of my knowledge 8mm VTR's have not been available for some time now. On the other hand there are plenty of Hi8 cameras and players available after market. eBay is a great source. Keep in mind that Hi8 cameras and decks will also play standard 8mm video tapes.
There are also many video tape transfer services that will transfer your 8mm tapes to DVD or other formats of your choice. Just Google "videotape transfer service"

DCR TRV140E is a Digital8 camera
CCD TRV87E is a Hi8 camera,
(Hi8 is an analog format)
the tapes are the same size, wont help, the recording systems are not compatible
send them to a lab service ?maybe if there are only a few
or ebay a Hi8 camera and transcode them yourself

its not a solution, at least it clarifies the problem

I was having the exact same problems, and I read a post on this website somewhere recommending that I just record a few seconds of video on a blank portion of tape and then the camera should start playing video normally again.

I tried it, and IT WORKED!!

any brand of hi8 or digital8 camcorder will play back those tapes but sony made a tape deck made to record and play back digital8, hi8, and 8mm tape. you can get here http://www.sonystyle.com/webapp/wcs/stores/servlet/SearchCatalog

Your camera playback heads appear to be dirty. You can purchase a head cleaner cassette from an electronics store or take it to a service centre where they will clean the heads.

Check that the tape itself is not damaged, as this can cause the same symptoms.

What's happening is that the tape in the cassette is being chewed on one side by the camera's tape transporting mechanism during playback, hence the distorted image and sound. The mechanism might be damaged (misalignment) or just dirty. Try not to play other tapes on this unit because they will become permanently damaged. The best way is to find another camcorder (if cleaning does not help). Note that some old cassettes of long recording time will exhibit this behavior more often because of thinner tape used.
