Open Question: I need to convert .koz files for music from the sprint or samsung cell phones for my computer . Any answers?

I have a Samsung 14" TV/VCR. I'd like to connect it to my JVC component system (including DVD player) so I can watch DVDs on the Samsung. I bought a set of component cables and I thought sure I had it connected right, but no picture (just blue screen). How do I get these two to talk to each other?
These are the connections I made:
JVC yellow ("VCR In") <----> Samsung yellow ("Video Input")
JVC white ("VCR Audio In") <----> Samsung white
("Audio Input")
Red (audio) connectors not used (obviously it's a mono TV).
The yellow and white "input" jacks on the Samsung are the only jacks on the TV.
There is also a yellow "Video Out" jack on the JVC but it doesn't work either.
What am I doing wrong?
Is it impossible to play DVD's this way?

Open Question: Looking for a ringtone maker that will let me create my own midi files or use my recorded files. Cable upload.

I purchased a cable to upload/download files from my Samsung phone. It came with software that will let me clip from recorded files or compose my own midi files, but I can't save them to upload them as ringtones to my phone. I don't want to have to pay for the service on my phone that will let me upload them off the internet. Any suggestions?
