Citizen C801DVR FAQ + Manual supplement

I acquired a new Citizen C801DVR recorder recently, and after struggling through the awful manual, I’ve created a manual supplement and FAQ for it here: http://www3.telus.net/IMSL/C801DVR.htm , which I hope will help others. This model is the same as the Electrohome 801EDVR, and very similar to the Cyberhome DVR 1600 and the iLO DVDR05.

The region hack for this model is Setup 8 1 0 5, the same as the Cyperhome DVR 1600 with the ZU firmware variant.

could you please tell me why when I use this Citizen C801DVR to record tv program with closed caption ,but lose closed caption ???
