That's them! Price is alright also, much cheaper than what I paid for these discs at least. Thanks for the info.
Amazon.de has MXL RG04 16 DVD-R media in stock btw. (according to the reviewer at least), price is ok also (21.99 EUR for a spindle of 25, shipping included): click.
Unfortunately not the DVD+R MAXELL 003s, but the Maxell DVD-R media is excellent as well (as can be seen here).
