nope.. I'm a complete gumby... mis sorting on my part.. my apologies...
let's try this again
ending in 19 was:
HD->SD (TV3 -> prime TV)
one ending in 22 was:
SD->HD (prime TV -> TV3), also tried to go on to the next HD channel (TV2) after that too.. audio disappears at that point, and black screen

OK - thanks
I'm fairly sure there's a real bug in TsReader.ax (probably in the NALU header parsing) which has been triggered by a change at the broadcaster end of things (as it's just started to happen). Need to do some more digging around the code....
In the meantime, attached is a hacked TsReader (based on the standard MP 1.2.2 version) which should force the video part of the playback graph to be rebuilt on every channel change - hopefully this will restore normal service until the problem can be fixed properly.

that's a bunch better, but still has some flakiness...
if I watch TV3 (HD) and change to SD channels (prime, four) it's fine.. all happy there.
but now if I watch TV2 (also HD, but a different mux* than TV3) it hangs (no matter what) after about 2 seconds
the logs is from turning on MP -> TV -> channel ->select TV2 -> right arrow (on remote) -> [ok] to enlarge.. it never got to the enlarge part.
TV1 (should be same mux* as TV2) is fine...
sorry if that makes things worse, but I wonder if it may also add more info to help troubleshoot :-/
* when I say mux.. I have no idea what I'm talking about, and have prolly got totally the wrong jargon, but there's like AFAIK 3 trandpondery freq thingies in NZ... tvnz, canwest and sky... something like that.. anyhoo TV1, 2 and U (and some others) are one group, tv3, FOUR (and some others) another, and prime (maybe some others?) is/are sky free to air channels

OK - the problem in the logs is an old bug with RTSP (which is not fixed in MP 1.2.2, but is in my latest dev versions) - try the attached version....

result.. that works.. thank you sir, you're a legend!
it is a little 'jittery' but it's pretty irregular and completely watchable (and also prolly down to the rubbish hardware I have).

OK - good.
This problem needs to be fixed properly though, so for my benefit could you:
1. Attach some logs with a few HD/SD channel changes please ?
2. Create a couple of very short recordings (10 - 20 sec) - one each from an SD channel and an HD channel - and upload/attach them please ?
Thanks,
Tony

will do tonight. just for clarification, this is an mp client only.. so recording (in theory) shouldn't have any effect (as it'd be on the main server).
issue does not present itself on the mp server but that has gruntier hardware, and is running on win7, not XP.

I need the recordings so I can create a pseudo timeshift file with a channel change transition in it - that way I might be able to work out what the underlying problem is in TsReader when handling your broadcast streams - that's the theory anyway
