I try to load a TS-record of HD TV:
Video: Video - AVC (H.264), Main Profile, Level 4.0, 1920x1080, 25.000 fps
Audio: MPEG1 - Layer 2, 48.0 kHz, 2 chn, 192.0 kbit/s

Avidemux 2.6.4 write: "Cannot find a demuxer for filename.ts"
Is it normal or bug?

You are using the latest avidemux 2.6.4? found here: http://avidemux.org/nightly/
Most likely this is a problem with the concerned mpeg-ts file. Is this only happening with this file or with several? If several: you're recording yourself the streams? What is it's origin: dvb-(c/c2/s/s2/t/t2), iptv, ....
Please provide a (5 second duration/ 20 MB size  recording) of the type that is causing this issue.
On daily basis I'm processing these mpeg-ts (SD/HD tv) streams. Om some occasions this goes wrong. Especially when something goes wrong in the stream: bad reception, smart card decoding, wrong info, ...
Upload the video (5 seconds/20 MB) to mega, rapidshare or similar web service and provide a publicly available down link to it (without a required registration to it)

I record IP-TV by program IP-TV Player. The problem with HD channel only (with any files from this channel). Nightly version don't open these files also, but Windows Media Player show video successfully.
Strange, but TS-video from the same channel, which I recorded by a hardware mediaplayer, Avidemux open normally. Possibly IP-TV Player writes incorrectly.

Here both videos (from software and hardware players)

With software recorded video with with vlc audio starts 1st and after some time the video.
Avidemux: the hardware recording is flawless, software recording is not loading. Index is not created.
MediaInfo tells both are similar for used audio and video codec.
Check if you can update your recording software or apply other settings.
Perhaps the developer can make more sense of it.

I lowered the detection threshold as a workaround, it is  a bug in the PMT parsing
Try with tomorrow nightly, should be okay

works now for software recorded to.

Unfortunately, the situation repeats again. Avidemux 2.6.7 (32-bit release) doesn't load HD video. Here one of short examples.
Recorded with IpTvPlayer.

If i lower more the threshold there will be false positive
Quick & dirty workaround

ffmpeg -i yourintputfile.ts youroutputfile.ts

and then open youroutputfile.ts
That processing is very very fast
