Please bear with me on this one, it may get a little long/complicated. I had posted this "workaround" for the chronic "missing timer programs" on another thread, but I believe it should have been in this one, since it specifically relates to the EZ-17. Here goes.
If you use WEEKLY timer schedules this pertains to you.
I will use an example to explain what circumstances will leed to a "failed" timer recording.
Lets say you have set up a timer recording for WEEKLY monday 7-9pm SP mode, also WEEKLY tuesday 7-9pm SP mode, and finally WEEKLY wed. 7-9pm SP mode(note times, channels, and disc type do not effect the outcome, speeds do indirectly if the disc gets mostly filled up, with insifficent time to record the next event).
You put in a blank disc sometime before mondays event, and power machine off. Monday's event will record just fine. NOW is the important part, if you change the disc(since it filled up after monday's event) BEFORE midnight monday, tuesday's event(and every event after that) will NOT record. UNLESS you power up/down the DVDR sometime tuesday(before the tuesday's event). Now if you were to have replaced the full disc anytime tuesday(before the event), tuesday's event would also record just fine. Also note if you power up the machine DURING tuesdays failed event(that is you notice it is not recording) and turn it on, and then power it off, it will start recording from the point AFTER you turn the DVDR off.
This "bug" only seems to be effected by WEEKLY sceduled events, since they do not "drop" of the list in the schedule. The machine keeps looking at monday's event until after midnight, that's why you must turn on/off the unit sometime tuesday. I think it somehow resets things. Just speculating?
I personally use WEEKLY events ALL the time(to save entering the event back in the schedule) I have about 9 shows that are on once a week, every week, so this "bug" effects me BIG time. I was missing events ALL the time before figuring out what was happening. NO previous Panny's that I have had, have this "bug" including ES-10, ES-25, and ES-30. Only this EZ series DVDR.
Note this "bug" also only happens if after say monday's event, the disc does not have enough space on it to record tuesday's event. If you are in the habbit of turning your machine on(for whatever reason) before the next event, you probably have not noticed this "bug". As for me I almost always fill up each disc with each seperate event, and was in the habbit of swapping out the disc right after the event is over, and never turn the machine back on, until after the next event, I always ran into this bug. You see I only record with this unit, and play back on my Sony up converting dvd player.
I hope I've explained this problem well enough to save someone else missed timer recordings. Since implamenting powering up machine EVERY morning, then turning right off, I have yet to miss a event. Note MANY calls to Panny to correct this "bug" with a firmware patch, have fallen on DEAF ears!!!
They dont even admit anyone is even having problems with missed timer events! I guess the don't read forums like this one.....
Note one more work around, you can also just unplug/replug the DVDR from the wall tuesday(in example) and that will reset things. I personally think it is easier to just power up/down the unit. I've toyed with the idea of putting the DVDR on a wall timer to interupt the power for 1 min. every morning, but have not done this yet.
On another note, I personally think it sucks, that this Panny has to be OFF to start a scheduled event. What a step BACKWARDS for Panasonic. Note if anyone else has figured out workarounds for this bug, or other scenerios in which this unit failed to record, please post those events.
