I see channel 9 is changing some of their broadcast from mpeg2 to mpeg4.

I use a DigitalNow 7164 PCIE card which I'm not sure can receive/handle the mpeg4 broadcast as well as the older mpeg2 ?

Also, will TV Scheduler Pro able to record the mpeg4 channel ? ... I am unsure if I need to change anything.

Thanks

The network has announced a radical shake-up of its current broadcasting channels. Its current HD channel Gem will shift to standard definition, Nine will introduce its new free-to-air broadcast lifestyle channel 9Life, and Nine will begin broadcasting its primary channel as a pair of standard definition and high definition channels.
To accommodate the extra channels that will broadcast, Nine has had to embrace a different compression type. From the commencement of digital TV broadcasting in Australia, networks have broadcast their signal with the MPEG2 compression type. To broadcast 9HD, Nine will employ MPEG4. This means that older TV sets and receivers may be able to receive a high definition MPEG2 signal, but are not equipped to receive MPEG4.
For most viewers, this shouldn’t pose a problem. It is believed that the average life cycle of a television set in Australia is about five years, with older sets that don’t support MPEG4 no longer being used as a households primary set. Of course, some viewers may still be using older TV sets.
When asked how many viewers may be negatively effected, Nine’s director of broadcast operations Geoff Sparke advised Mediaweek that it’s “hard to say. We believe that MP4 decoders have been inbuilt since about 2007, and on average about one million panels are sold per year. So I would suggest the main screen in about 90% of homes are MP4 capable”.
Viewers who cannot receive the HD signal will be able to continue to watch Nine as a standard definition channel.
The shift to adopt MPEG4 compression broadcast does bring with it a significant video quality upgrade. Currently the Australian HD signal offers a 1440 x 1080 resolution, but MPEG4 will provide greater clarity, with Sparke confirming they will broadcast in full HD 1920 x 1080.
Nine will re-stack their channels on 26 November 2015. Some viewers may need to re-scan their television sets to receive the new channel lineup.

In theory I think it should work. I am assuming the TS will capture the same and encapsulate AVC/h264 video instead of mpeg2.
The demuxer used will need to be able to handle the streams correctly to play it though.
I also would assume that dvrms will not work for mpeg4 content.

As to whether it WILL actually work though I have no idea. Will have to wait and see.

Anyone had any luck recording the new 9HD?

In Melbourne, it looks like the only settings change from the former HD channel (GEM) is from video PID 512 to 513.

I've tried TS-Mux recordings without success (the resulting file sizes are too small).

Edit: still running DVB Web Scheduler Pro 6.0.0.0 from 2009 :-)

Edit 2: Just found the OP also posted this here:

Yes, no probs. Latest version of TV Scheduler Pro with the latest stationdata.list.
Also used VideoReDo to auto "Quick Stream Fix" the recorded stream (.TS file) to fix up any o.t.a. glitches and make it into an MP4 (it does not force re-coding).
The mp4 played in the latest version of "media player classic home cinema" (from videohelp.com).

The only bugbear for me is that the 9HD broadcast mpeg4-AVC uses cabac as an encoding parameter (which works a decoder harder during playback, if it can handle cabac) - and my WDTV Live media players can't handle cabac, so I need to re-encode the .MP4 into another one without cabac (damn).
