I have a DVD recorder that has a DVD-RAM dvd in a cartridge. I just bought a portable DVD player that says the only format I can use that isn't finalized is a DVD-RAM without the cartridge. Mine has a cartridge but it says the DVD can be taken out of the case. My first question is - how do I use the DVD-RAM? Do I have to use it in the cartridge to record on the DVD recorder or can I take it out of the cartridge to record? How do I get the DVD-RAM dvd out of the cartridge? Do I have to initialize the DVD-RAM before I can use it? Sorry about all of the questions, but I am at a total loss. I can't find the answers on the internet and my recorder's manual is useless. Thank you.
