Cutting out the barcode from a regular chocolate disc, and taping it over the barcode of the professional disc works great, and brewed it. Just make sure for the chocolate and liquid discs, you use a barcode from a chocolate or liquid one. It pumps extra air near the end to get all the liquid out of the T-discs. Trying the barcode from a coffee disc, still left a bit of liquid left in the chocolate disc.
So with the barcode taping modification, you can use the Tassimo professional T-discs in the home brewers.
