How to switch from sp to lp mode when playing back?

I dont think u can do that on playback only on recording, it works auto.

May be you recorded it on LP, LP recording are sensitive to interchangeability issues or it could beyour JVC's LP heads are weak. If you have an idea on how to adjust pole base, try to adjust supply side on your JVC(left side pole base) while playing and observe the sound while adjusting it. Be careful not to touch parts at the sorroundings,pay a lot of attention while doing this. If you do not have background in this field, let the pro do the job. Good luck

red carefully the manual on page 45

check the mode. if it is in record mode, change to player mode

If you are referring to the JVC GR-DVL520, yes it does play Mini DV tapes, as well as records to them. It will not play Mini DV tapes that were recorded on an HDV camera. HDV is used by any Mini DV camera that records HD video.

In 1990s Sony camcorder records movie in analog format so playing in digital camcorder like DCR-TRV730 doesn't mean it will be converted in digital format and you can not import file in PC for editing purpose. You will get analog signal while playing back old cassettes.

Regarding SP, LP speed, its decided at time of recording. Camera sens SP or LP automatically in playback and set itself accordingly.

If you want to convert old cassettes into digital format, connect our camcorder to DVD recorder and burn DVD which is digital format, copy DVD files in to PC and do desired editing.

Please use Mini DV Video head cleaning cassette as it seems video head is dirty / clogged in camera.

the clicking is from the capstain turning the tape -- and perhaps the metal cage holding the tape.. if it is bent then the movement of the capstain may be pushing it in an eccentric fashion.

send it in for repair.

mini DVs sometimes can't be access using usb interface, try to look if u have a firewire interface, be sure your laptop supports IEEE1394. power dvd is the best player for dvd files. -r means recordable, not rewritable (rw). if ur not familiar with video editing, you may not be able to burn it to disc, but you can play and watch everytime.
