Can't open .mpg file from USB TV tuner

Hi all,

I have recorded a couple of TV programmes onto my laptop using a USB TV tuner. The file is saved as a.MPG file and plays fine using VLC Media player but VRD doesn't recognise the file as a valid video file.

Any suggestions?

Cheers

Check the properties of the file in VLC and mediainfo.

If you are recording type MP4 part 10 video, it is not supported in TVSuite V3.

Can you please use MediaInfo, switch to Text view and then copy/paste the info here. The above isn't quite enough to tell if it should work or not.

Hi Dan,

Unfortunately I can't do that, I just get an error message - "Unable to open files".

I can open other .mpg files.

I used Mediainfo to analyse a file that works -

The only difference I can see is the OverallBitRate/String and BitRate/String.

Hope this helps.

Generally you can "trim and copy source file" without opening the file first.
Start VRD, go to "tools", select "trim and copy...", select the file.
It will trim and copy any file - data, text, pdf, exe, etc.

Also, as a Hauppauge user, some versions of the WinTV application had been known to insert garbage at the start of the mpg file.
(you had to trim off the first few MB to get it to open - I don't use that app any more myself)

It will trim and copy any file........except this one!!

What you suggested above is what I did.

The software was that came with the device was BlazeTV.

Hi Dan,

Working on the theory that the programme should do what you say it does (trim and copy any file), the odds are that the problem was with me rather than VRD so I have had another go at trimming the file, this time with success.

I have uploaded a 100meg file as requested, hopefully you can sort it out.

Cheers

The file you sent opens fine in TVSuite v4 but not in Plus v3. Not sure why. I'm not actually able to build v3 because it's older then my employment here. I'm having DanR look into the problem.
