I picked one of these up in Richer Sounds recently. When it works it seems fine, but it has an unpleasant habit of locking up when it is turned on with a disk in the tray. Sometimes it says Philips and stops there, sometimes it also throws what looks to be a hex error code (AE3-something from memory). After that the system refuses to respond to any controls except sometimes the power off. It can eventually be restored by pulling the power cable and fiddling with various front panel controls while repluging but this often results in a loss of installation data after which it has to find all the tv stations again etc. Has anyone else seen this? Would a firmware upgrade work or am I better off just taking it back? Thanks!
