Well, if its any encouragement (?), although OpenPli is very fast normally for most things, when I flash an image, it takes about 15 seconds (after settings are restored and reboot) at least to settle on a time (currently on Transponder and 1st channel is BBC1 HD)
... it sits there on the year dot ... for a long time...... never had that with ViX (before hwclock or after)
