hi,
is there somewhere a patch that would remove the break when the broadcaster uses "dynamic pids" (such as YLE). Now, when a programme starts at YLE, they change the Audio PID number, leading to VDR re-tuning or something, that leads to a 1-2s break in the show. There is no change in frequency, so I don't see any reason why there is such a break.
Or is this a problem of co-operation with vdr-xine, instead of tuning the card?
yours, Jouni

VDR simply "retunes" whenever the PIDs or other parameters change. It just keeps things simple ;-)
Changing the PIDs while a broadcast is already running is not a very good practice...

I appreciate this KISS approach.

Well. They probably think it is very much using the possibilities of the new technology. Luckily they do not switch them during news broadcasts, when interviewing foreign people. Now that would be a nightmare.

As a quick fix just disable the pid updates ("Channel update: no/names only"). Yle is always using the same pid numbers although they're switching them on and off, so you can easily fix these numbers in your channel.conf.

Thanks for the hint, but this is a pain.
A quick search found the "confidential" A-PID list from here: http://www.digita.fi/binary.asp?path=1840;1852;7462;11558
Seems they are rotating between three apids on each channel. How ingenious :/

Tried this, but it seems it loses the subtitling PIDs. Is there a way to get both - subtitling and non-breaking TV viewing?

It might be interesting to learn why they do this "PID cycling" in the first place. Have you ever tried contacting them and asking why they do such a stupid thing?

Different programmes have a different number of languages, so the number of active pids changes. Isn't that correct behaviour?

Sure, but why "cycle" them through various values, and not use the same ones for the same languages?
As long as the PID switch takes place outside a show, that's of course ok. Switching them *inside* a show is IMHO not a good idea.

As far as I can see they keep them the same, and VDR retunes just because the number of tracks changes.

The change of active PIDs takes place when a show begins, causing 1-2s of stream to go missing due to the retune as Jouni described in the initial post.

It sure wouldn't hurt if they changed the PIDs a little earlier. Other channels do that.

True. I don't know, however, if it is reasonable to request YLE to change the pids before the actual programme stream starts.
It seems things look clearer. When the show starts, then within 1-2 seconds the break starts, then there is the break of 1-2 seconds, after that everything is smooth. The biggest actual annoyance is that nowadays the titles are often after the first scene, so there is a part of the actual show right in the beginning. It often happens that about 30 seconds of subtitling is lost at the beginning of the show; probably as it is sent during those precious first seconds.

Couple of weeks ago I reported to the Hugarian Hello HD provider, [1], that they are not sending the correct encoding for their EPG content (ISO-8859-2). Actually they did not send any encoding information, so VDR used the default ISO6937 encoding, which was wrong. After I send a mail to them, they replayed that several other users with Technisat receivers complained about this, and they did not send EPG encoding info until now, because official HelloHD STB-s were setup to use the right encoding.
From 20 november Hello HD started to send the right EPG encoding
inforamtion [2], and since then the EPG works fine on VDR.
So the conclusion is, that you can try to send a mail to YLE, maybe there is somebody there, who cares about this.

Oh, I forgot that the spids aren't present in channels.conf, so you need to patch the vdr in a way or another. I guess the quick'n'dirty fix would be adding support for spids into channels.conf...
