Freeview HD ( DVB-T2) tuners finally becoming available

[aardwolf2]

Martin, thanks for the advice, I got scrambled sound on the right channel for some reason (playing on the PC gives the same results so it's definitely the file) so I changed to acodec=mpga,ab=128 and it's fine, I'll play with the settings to get the best results once I know it's stable. The reason it wouldn't encode when I tried to do it manualy from vlc is that I had sample rate set to 44100, and it wouldn't produce a filter so no audio output. I've created a postprocessing.bat so I don't have to do it by hand after every recording, just checking it doesn't break SD recordings. I'm using vlc 1.1.4.

<edit>I also had to add --play-and-exit to the vlc command line to exit once it's finished the transcode so it can run the rest of the batch file, otherwise you have to shutdown the vlc progress window manually, and I had to make postprocessing.bat run as administrator to write the transcoded file back over the original. Hope this helps others.

Update: Can't get postprocessing.bat to run as administrator so I reencode the file, then can't copy the encoded file back over the original. Tried following the recommendation of creating a .lnk and giving that administrator permissions but as it's not postprocessing.bat it doesn't run automatically, more work to do.

You need vlc://quit to close that command prompt. The Recording Service in GBPVR and NPVR run at Local System level so it sounds like you have another problem.

I'm not good at post processing files but if you rename the input name to a temp name and then have vlc transcode to the input name you wouldn't have to copy it.

I think I've got it working now, had my first bash at (hopefully) setting W7 file permissions, give me chmod any day. I've maintained the "encode to seperate file then move back" approach as if it goes wrong the original file is left intact. It's my first attempt so a bit basic, all derision gratefully received, but my PostProcessing.bat looks like this.

@echo off
cd %~p1
"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" %1 out=#transcode{acodec=mpga,ab=192,channels=2,samplerate=48000}:duplicate{dst=std{access=file,mux=ts,dst="temp.ts"}} -I dummy --play-and-exit
move /Y temp.ts %1

I originally used a static location for temp.ts, but that has undesired effects if two encodes are running at the same time, and --play-and-exit works so I''ve left it.

Thanks for all the help, if only the a100 supported HE-AAC.

Just an update.
Got my nanostick a few days ago (and nano is a good description) as suspected no IEC>MCX adapter. It is included on the spec at PCTV web site but not on the DABS and others sites. However, a crawling and grovelling email to pctv tech support provided one - thanks guys.

The device works a treat, is sensitive and doesn't crash the system like the nova-hd-s2's seem to do. Tried recording all four HD channels and no signs of hickups.
It is quite slow changing channels though.
