Toshiba RD-X7 is a new exciting HD DVD recorder that is capable of recording high definition video material to standard DVD discs. They do this by using the much more efficient compression technology MPEG4. On a standard DVD-R the recorder can fit 2 hours of high definition video (I’m not sure in which resolution, but at least 720p), and on a HD DVD-R up to 6 hours can be recorded. We will probably see an official announcement from Toshiba regarding the RD-X7 in the next couple of weeks.
