Magic TV seems to be working fine without a rescan

Zinwell 620HD is having major reception problems with TV3/C4/TV3+1 even after a rescan.

I had a couple of freezes on tv3 this morn during ET. One it changed to data service on the TV, then the radio icon appeared, then 10-15 secs later a breaking up juddery picture for a bit then it was fine, the second one it was just an audio glitch then juddery for a few seconds.

Nety: I have always set the channels up that way. There is an option in EPG collector to auto assigned the channels but I have never used it. You only have to set them up once, well unless they decide to change things around like this again..

Hi, Im not too sure if I had made my problem clear.

Before the rescan EPG collector would automatically collect the EPG at the scheduled time and upload and populate automatically to Media Centers epg, pretty much working 100%

In the guide settings there was about 44 different listings ie TV One and TV One-EPG collector of which I had TV Oone-EPG collector selected.

But now after the re-scan TVNZ channels don't seem to auto upload or populate to Media Center EPG and in the guide settings there are only 26 different listings. In the guide listings there are no *-EPG collector options for any TVNZ channels.

I use Media Center 7 and receive UHF from Kaukau

Thanks for any help

I wish TV1 and TV3 fix up there Plus channels I have been told they use the same CRID, I cant record +1 channels at the delayed time, it just not my STB as I have seen other posts even from some one with a Panasonic recorder..

Ive been told by DishTV that it a Freeview fault.

Any one know any better.?

From the information I have seen, the TV3 DTT service has a service ID of 1300 and TV3+1 has a service ID of 1302 so they are different

From what I've read, it seems that Auckland is not affected. Is this right or did I misunderstand? I use the Pinehill transmitter.

Ive take a couple of screen shots of my issue to make it clearer.

Picture called EPG1 shows that beyond a about an hour TVNZ channels have no EPG whereas the Mediaworks ones do and also have the little logos that EPG collector can upload.

Picture called EPG2 is my guide settings, under the listing menu. The two at the top have the EPG collector end whereas the 2 x TVNZ channels there is no EPG collector option. Furthermore before the re-tune there were 44 listing selections and after there is only 34 of which I believe are the missing TVNZ channels.

https://skydrive.live.com/redir?resid=9C43DA81E65F469B!142&authkey=!ANPvYQmGPo9UX-M

I have not changed any settings what so ever only did a rescan as per the original post.

Its so frustrating as all I did was a re-tune.

If this is in the wrong place please redirect me to the right place

Thanks

Just a question on C4.

Whilst I can view the channel OK, and the EPG Collector "see the channel", Im not getting any EPG data for it. Is anyone else finding the same?

Hey does anyone know exactly what was changed in the way TV3 broadcast?
Most of the info appears to let you know it was coming, but not what the changes themselves actually were.

Reason being it looks like the Zinwells/JC Matthew PVR's haven't responded very well to this at all. I'm curious as to what's really confusing those units?

Mediaworks have implemented regionalised their services into 4 areas, I guess with similar boundaries to the TVNZ areas (eg Auckland & Northland, Central NI, Lower NI and SI). This has happened on both their DTT and DTH services. The Freeview Transmission rules allowed for this (see
pages 105, 106 & 107) split to occur in the transport stream and service ids for set up.

Is this the first time this has been implemented on terrestrial?
(I know TV1 has been doing this for ages on sat).
Point being, what's so special about this that it stuffs up Zinwells etc, unless we're assuming they skipped over this bit when they originally developed the code?

TVNZ are already regional on DTT so not the first time it has been done on these shores.

Why the Zinwell boxes are not happy I can´t give an answer for. It just turns into speculation unless someone from Mediaworks wishes to comment.

I don't know, but I'm happy to speculate.

Somewhere on GZ, I recall reading that some users had observed a reduction in video quality which stemmed from increased video compression being applied. This to reduce b/w requirements to make room for the extra feeds.
I always felt that the Zinwell/JC Mathews boxes struggled for processing power, either through lack of CPU grunt or available RAM.
I'm wondering if the extra compression increases the workload on these resources.
Further one subscriber recently showed CPU Usage figures that had higher requirements on Media Works mux than on the other streams, which seems to support my conjecture.
The lack of grunt would obviously show up first on lower priority tasks, such as responding to Remote Commands and displaying the EPG. These tasks seem to be the main cause of complaint. Also the supplier's recommendation to unplug the Aerial during replays (to relieve the CPU of decoding tasks) seems to work.

If this is true then I can't see much chance of the suppliers fixing the problem, other than by extensively re-writing their code to make it run more efficiently. Will they go to that much trouble for a discontinued product?

I doubt that the CGA requires an electronics manufacturer to guarantee future proofing of their device to allow for system changes.
Neither would the blame lay with Freeview.

Yes. This is just speculation, but not, I think, totally wild.

Can you give me next weeks lotto no's

"Zinwell have advised that it will be several weeks before a solution can be made available as an almost complete re-write of the system software is required to handle the recent changes introduced by TV3."

I think they'll be stuck by the consumer guarantees situation. Whilst it's now discontinued, it's still within the period for which it needs to work. They're still in the 'either provide an alternative or refund you the money' zone, so yes I think their first point of call has to be to try and make the current hardware work.
