DVD-R Media

I recently got a rebadged A05 DVD-R. The drive itself came with a unbranded PRINCO made DVD-R. I also bought a 3-pack of Memorex TAIYO YUDEN made DVD-R. I tried both and the A05 recognized the Memorex easily, while it takes about 1-2 seconds before the Princo made DVD-R. I have had a cd burner and know that sometimes(not always) cheap prices comes with cheap quality. The Memorex DVD-R average out to about $3 a disc and thats kinda expensive for me. I've checked out the prices on pricewatch and the cheapest DVD-R are usually unbranded Princo made ones. I also looked a Ritek brand which are about $1 a disc. I would like to know of anybody has any recommendations for a cheap, quality DVD-R brand. I just want some feedback, because I am using this to archive, not just to burn a cd and chuck it at the end of the week. I bought cdrs that wouldn't read correctly after a year. I don't want that to happen with my dvds. Thanks for reading my post. Please tell me all of the following information if possible:

Your DVD-R burner: Manufacturer
DVD-R media Brand (ie Memorex)
DVD-R media Manufacturer(ie Ritek)
DVD-R media speed(1x, 2x, 4x)
DVD-R media Price
What you use it for?(movie, file backup, ps2 games, etc)
Any compatibility problems
After you burned the DVD-Rs, how long was it stored and if it has any issues with long term storage.
