i have a sony dcr-trv250 (i know, not the best for video/editing) but it does not play tabes that i put in it. It shows a little icon (box with a triangle on top of it...) and beeps constantly. Anyone familiar with this type of problem?

is the tape record tab on? if so, slide it to the "record" position.

it does this whenever the camera is in "record" or "vcr" modes.

no no, i mean on the tape itself. theres a little tab you can slide on the tape. you can also look in your manual to see what that icon means.
