Converting HDTV stream into WMV or AVI

[naderro]

I would like to convert HDTV streams that I download over the air and convert them to something managable for Creative Zen (AVI or MWV. I have used "MediaCoder" and "Super" but both can't handle it! Can anyone suggest what I can do? Is the Codex an issue here?

HDTV only means higher resolution than SDTV. What video and audio codecs are used? What kind of container does the your recordings have?

At least what file extension do they have? And what is the source of your HDTV signal and how do record it?

And what is Codex?

Thank you for the response.
In the "properties" for the HD channel in the Mediacoder it says the following:-

container:mpeg-ps
video(0):mpeg1
bitrate: 12000kbps
resolution: 704x480
frame rate: 59.94
Audio: AC-3
Bitrate: 480000hz
Channel:2
The odd thing is that I can convert the "pbs digital" (non-HD) which comes up with the same parameters but not the HD channel !
I tried using "super", to no avail.
Also, not only can I not convert the files, it seems that I cannot even play them using eithet Mediacoder or super.

Do please let me know if you need any more info...........

Thanks,

DVD videos have 720x480 resolution, so 704x480 is not HD video.

There could be a problem with MediaCoder or with the way your video is recorded.

Try some other audio/video converter. You can use freeware virtual dub or commercial Cucusoft Ultimate Video Converter, Nero Recode and many, many other programs.

If you decide to use commercial software, don't buy it right away. Test a free trial version first to make sure it works for youl.

Thank you so much. I will definitely try some of the programs and let you know.
Just curiouse, why would the AVI.net convert the regular digital tv and not the HD? The only difference I can see in the analysis sections I sent in earlier emails is the bit rate (2214 Kbps vs 6091 for the HD) could that be the problem? Is there anyway to reduvce the bit-rate?
