My tape deck on an old CCD-TR91 Camera will not go down when an 8 mm tape is placed in it. Consequently, I cannot upgrade my home videos to DVDs. Any suggestions?

Try ebay

8 mm and the newer super 8 mm video tapes are different. You can't use super 8 mm in old player. And old tapes won't play well in new super 8 mm players. Like Sony!

hi!
The problem is with the CCD which is the sensor when it is defective the pictures get disturbed also.Please replace the CCD from any service center,

Try to clean video head with cleaning cassette, if same position than video head need to be change

You want to purchase the Handycam CCD-TRV37? If so that is 8mm. If your referring to another camera give me the model and I will let you know. Though I would consider switching over to mini-dv. The quality is alot better and is the standard now so there are many models available.
Thank you,

Were your tapes recorded in extended play? Sometimes that will make it impossible for a different tape deck to play it back correctly. The tolerences on Hi-8 are very small so it is possible that a tiny alignment difference will make it impossible to play back a pre-recorded tape. Try fast forwording and rewinding the tape and try it again. Also try playing it from different parts of the tape. Go to the middle of the tape and try it there.
