Hi all,

Which mux should i set if i want to use both pc clients and the NMT and, most important, where can i find it?

Thanks a lot

Definitely not dvr-ms. I use TS Mux but sub has said he has to fix it for some streams when he has some more time and it is harder to setup on the PC.

But where can i find 'TS Mux' ?It is installed automatically with GB-PVR.

I use TS Mux but sub has said he has to fix it for some streams when he has some more time and it is harder to setup on the PC.Actually I've read a couple of things in the libhdhomerun thread that makes me think its not a problem in the TS files that GB-PVR recording, but rather a bug in the PCH that doesnt like the way some ATSC streams are identified in the transport streams generated by the broadcaster. The fix would the same as previously suggested though, with me having to rewrite the PMT header in the stream to make it compatible with what the PCH could play.

Why is that? Doesn't the PCH play DVR-MS?

No it is yet another proprietary MS format.

There is a difference, at least with the file I sent you. When I saved the stream with TSReader it plays on the PCH, when it is saved with TS Mux there is no audio.

OK, so if there's no sound with the TS Mux then what's the solution? Cyberlink to mpg? I guess I'm confused now...I kinda thought that the PCH was pretty much a super MVP but it sounds like that may not be the case. I haven't followed all the PCH discussions so perhaps this has already been discussed...

OTOH, I have an HD-DVR on order (I think) so once I get it most of the HD recording will be in H.264 format (at least that's my understanding) but I still may do some OTA ATSC recordings.

All this stuff is pretty confusing to the somewhat casual user. I think we have too many standards... :)

I think its something to do with transport stream recordings where an unneeded audio stream was dropped at recording time, but header not being updated to say that audio stream isnt present in the file. This is perfectly valid, and they play fine on the PC, but the NMT does like it, and doesnt seem to let you switch to the audio stream that is present.

The TS Mux recordings I've done with the HD-PVR work fine, and give the correct audio.

MartinThis is because either they'll be including both audio streams, or rewriting the PMT header to indicate there is only the one audio stream.

Recording with TSReader gives the option of selecting all audio streams or just one and of the course the entire ts in the high end product.

I started the new TS stuff yesterday, and its not too far off being complete. I assume you can reproduce the problem there? If so, any chance you can test it for me?

Anytime, I'll be testing it with the next PCH firmware too (no LATM support). I wouldn't mind a new NZ sample too with just one audio channel. That BBC guy's cough is getting annoying anyway.

For those that have had this missing audio problem with the TS Mux, I've resolved this problem earlier today. I'll post a patch in the next day or so.

I currently record to my server using ts mux. I can not watch live or recorded programs from my client. When I recieve my PCH and get it working, will I be able to stream ts files to it?
