The writers buffer is 2Mb and is set to this in the default config file. Will look into what cdrecord thinks it is.
? What's wrong with 10x? The other thing I've seen that can cause these wonderful errors is cdrecord incorrectly detecting the amount of buffer in the CDR drive.. Check that it's right. The BTC's from memory have 4Mb (or at least my 32x does) if this figure is detected too high cdrecord (and therefore xcdroast) will have problems...
