From reading other posts, it seems Memorex isn't the best brand to buy for DVD-R's for the Panasonic DMR-E30. Are there any other brands that I should stay away from? shop4tech.com has some good deals on a PrimeDisc 50 pack of DVD-R's ($79.50 plus free shipping including the Keep Cases!) and they even sell 9.4 GB DVD-R's (double-sided DVD)! Are they any other on-line retailers worth checking out? Thanks.
