Please help.

I tested WinTV-HVR 1300 card. It can only receive anologue TV and digial Radios (eg. DVB-T Source Radio NZ National and DVB-T Source Radio NZ Concert), but not Freeview channels. However, it did pick up all the Freeview Channels when it scanned the DVB-T signals such as:

TV ONE, DVB-T Source TV ONE at 53800
TV2, DVB-T Source TV2 at 53800

I use WinTV software to watch TV.

Please help.

I read that. But did not solve the problem. I have PowereDVD 7 installed and use WinTV for DVB-T receiveing.

WinTV doesn't support AAC+ or H.264, i.e., you cannot use it for DVB-T TV.

Cyberlink Powercinema came bundled with my HVR-2200, this has AAC+ support and seems to work okay.

Well WINTV 6 came with the card. I thought it should work.

Anyway, I just tried DVB viewer. Now I have this error: "Cannot load source filter, error:0x80040154 class not registered"

as was covered, WinTV won't work, fullstop, end of story.

i can usually use DVB-Viewer with my card (HVR-1300 too), but it seems to be playing up now. Stupid filters etc I think.

Then it is so strange that WinTV does not support DVB-T since it is the software come with WinTV-HVR 1300 card. As I said in my request for help, WinTV did scan the signals, but failed to show them. I also guess it was a filter problem. however, there is no way to config the filters for WinTV.

I now can get the Freeview signals with DVB Viewer, but I cannot use the on-board MPEG2 encoder with DVB Viewer. therefore, I hope somebody knows how to get it work with WinTV.

WinTV does work with MPEG2 DVB-T, but not the MPEG4 DVB-T that we use. This is why you can get radio, as that is MPEG2 I think.

The MPEG2 encoder is for analgoue stuff, means that when you record stuff from VHS/Sky via analogue, all the encoding is done onboard, which leads to less load on CPU, and less blippy recordings.

I wish I knew it earlier.

I have bought a useless card, then. I thought it would be used for our NZ Freeview DVB-T recording via onborad MPEG2 encoder. So it also means that even though I can use other softwares, like PowerCinema, or DVBviewer to get NZ Freeview DVB-T channels, all the decoding and recording will be done by software!!!!!!!!!!!, which requires lots of CPU power!!!!!!!!!!!!

Onboard mpeg2 encoder is used for analog PAL BG recording only.

DVB-T H.264 TS (transport stream) is saved to hard drive in its native format - why would one decode and then reencode, this doesn't make sense. H.264 decoding in hardware on playback is via a suitable graphics card. All this information was available in the approapriate threads on Geekzone since late 2007 or even before.

Thanks for the clarification.

Is there a way to use the Onboard mpeg2 encoder for recording of DVB-T H.264 TS?

The mpeg2 encoder is only useful if you want to convert a program to mpeg2, which is basically never in the NZ context. It's not needed to record the digital Freeview signal. Freeview uses H.264 compression (sometimes also known as mpeg4), which then has a bit of stuff wrapped around it to transport it (hence Transport Stream, or TS).

You do not want to decompress the H.264, and then recompress to mpeg2. Recording a program just saves the (already compressed at the broadcaster) H.264 TS directly to the harddrive, pretty much as it comes from the HVR card.

With Freeview, all the Hauppauge and other brand tuner cards are just used as dumb devices. They tune in to the signal and send the raw digital bits to the computer. They don't interpret, process, or attempt to decode the signal in any way. That's left entirely to the software you use, e.g. MediaPortal, GB-PVR. That's why just about any tuner card will work here, even though the manufacturer doesn't explicitly support H.264.

medp7060: Thanks for the clarification.

No, for a variety of reasons. A couple of the key ones:
- the DVB-T signal arrives already encoded using the much more efficent H.264 (MPEG4) format,
- the hardware encoder in the HVR1300 is hardwired to the analog inputs,
- the hardware encoder only handles standard definition so wouldnt be able to encode our highdef channels anyway
- etc...

You mentioned CPU as one of the reasons you wanted to use the onboard MPEG2 encoder. Remember, this DVB-T signal is already encoded, so it only uses a couple of percent of CPU to record - no heavy CPU work required. All the CPU required is really for playback, and this HVR1300 device didnt have a hardware decoder, so was never going to help with this.

What are the specifications of your system?

The reality is that decoding the H.264 braodcasts in new Zealand requires a relatively powerful computer (minimum dual core) with a video card capable of H.264 hardware acceleration (NVidia 8500 or upwards) and appropiate software. It also requires TV software and a codec such as the one that comes with PowerDVD7 or 8 that is capable of H.264 hardware acceleration.

You haven't been the first person to come here to Geekzone with problems and won't be the last - the reality is that with the exception of the HVR2200 card and Nova 500T cards that comes with PowerCinema everything else on the market is IMHO a waste of time. There are quite a few companies now selling cards/usb sticks in the market are claiming their software "works" with NZ's H.264 broadcasts but with the exception og the Hauppauge units I've seen nothing capable of H.264 hardware acceleration.

Supplies distributing these products really are doing their customers no favours.

Now the question: is the FreeviewHD signal directly recorded (or saved) as its raw format of H264/AAC? If that’s the case, it would not require high CPU, i.e. a rate of 8Mb/s for FreeviewHD is not a big burden for a average computer. But I found that there were A/V synchronising and frame-loosing problems for replaying FreeviewHD contents (1080i), but not the 720i contents.
