There is currently a new software update being released to both "series 1" and "series 2" DirecTivo boxes. The update fixes issues with audio dropouts on the optical output, a closed captioning problem and the problem with some DirecTivos locking up at 28% on bootup. The new software version numbers are 3.1.0b for the "series 1' and 3.1.1b for the "series 2". The software update also changes HDVR2 boxes to HDVR3. No one is quite sure why. Rumor has it that it will take approximately three weeks for all DirecTivo boxes to be updated to this version. The roll out is totally random and you can not force your box to update.
