Memorex offers a full line of DVD RW recordable blank media. The 4X DVD RW media packs can reliably be rewritten up to 1,000 times and can store up to 4.7 GB of data, approximately 120 minutes of video. Consumers can transfer home movies from VHS or 8mm cassettes, back-up computer hard drives and large files. The new 4X media is backward compatible with a firmware upgrade, which can be downloaded at www.dvdrwservices.com. With larger storage capacities on DVD media, users can store at least 6.5 times more than on a CD-R/RW. DVD media allows the preservation of favorite videos, precious photos, valuable data and an entire music library. The DVD RW disc was developed for DVD RW/ R drives.
