I have read with interest the problems flashing to 1.57, but here is another interesting problem that perhaps someone else has had or could give a solution. After flashing to 1.57 with Pioneers official update, all is well to read or write any brand of DVD but it will not recognise or accept any brand of CD-R now!. I tried re-flashing with DVRUPDATE 0.9.EXE and files, again no problems flashing, again no problems with DVD but same problem with CDR's. Pioneer do not want to know because I used DVRUPDATE second time round. Anyone any comments.
