The Sony DCR-TRV30 is a miniDV tape based camcorder. Connect the camcorder's DV port (not USB) to the computer's firewire port (not USB - the firewire port was not included in the box).
Link to the manual (even though you said you have it):
http://www.docs.sony.com/release/DCRTRV30.pdf
See page 5 for what was included in the box.
We know nothing about your computer.
From the digital tape to the computer:
With the camera connected to the computer with a firewire cable, and the camera in "VCR" mode, launch the video editor in the computer and Import or Capture the video. The high quality DV format from the camcorder will import assuming the DV port still works (and the computer's firewire port is working properly).
From the Memory Stick to the computer:
Recording video to the memory card will result in less-than-standard definition (generally very low video quality) compressed video that will be in MPG format. If you go this route, the video needs to be transcoded before many video editors can deal with it. There are lots of transcoders out there.
My opinion: If a deal seems to good to be true, then it probably is.
But we don't know what you know about the camcorder.
Good luck.
I need a cheap camcorder with night shot. I have read great reviews about this older camera,Sony DCR TRV30. I have an opportunity to buy one extremely cheap, the problem is all it comes with is power cord/charger and 1 battery.My question is what else do I need to buy to be able to load videos onto pc? I found manual online and I have batteries and external charger that will work with this camcorder. I am currently running windows vista home edition. I don't understand too much about camcorders so I need someone to hold my hand and give a list of what I will need. It is such an incredibly good deal I hate to pass it up. I can start list I know I have to buy tapes,but thats about all I know. Any help would be greatly appreciated. Thank YOU.
