Pixelz:

I have also found you can only convert wtv files on the system they were first written.  If you copy them to another system and try to convert them locally, it fails.  I guess there's some Protected BDA and/or DRM nonsense in the wtv files.  In any event, I know there's a lot of rubbish present as my output dvr-ms files are over 40% smaller in size !!

Many thanks to the author of this tool, BTW

The application just "plays" the wtv into a dvr-ms.  It should work on any system that can playback the files, it will not work on a system that does not have the TV Pack installed. 

When I convert a WTV to a DVR-MS via cmdline the output plays fine in Media Center, but I have no audio when I play the DVR-MS in Media Player.

I have audio when I play the .WTV in Media Player.     Something not getting written correctly to the DVR-MS?

 

In graphedit both graphs for WTV and DVR-MS are using the same MPEG Audio Decoder so I assume they would play the same.

Media Center uses filters with very low merit (they are configured in the registry) to playback tv files.  The filters that show up in graphedit (which WMP will use) are not the ones that VMC uses (at least not on my box).  I found that audio is somewhat sketchy with the Microsoft MPEG-1/DD Audio Decoder on machines with the TV Pack installed (VMC uses a new MS A/V filter set), but it works fine on pre-TV Pack boxes (I've tested Vista SP1). 

The video samples had some extra stuff that needed to be removed before the files would convert, it's possible that the audio stream is similar.  This aspect of todvrms's feature set was intended to provide backwards compatiblity to machines that did not have SBEV2 installed, and may not work perfectly in all scenarios.  I will look at it though.

Not sure what to make of this.  Before I started I noted the following:

.WTV plays fine in Media Center (64-bit)
.WTV plays fine in Media Player (64-bit)
.WTV plays fine in Media Player (32-bit)

I ran todvrms.exe on Windows Vista x64 and discovered the following:

DVR-MS plays fine in Media Center (64-bit)
DVR-MS plays fine in Media Player (64-bit)
DVR-MS NO AUDIO in Media Player (32-bit)  ***

I checked both graphs (32bit & 64bit graphedit) and they both show the same audio decoder - "MPEG Audio Decoder".

I found that HD .WTV files with AC3 audio convert just fine and play back correctly in both 32-bit & 64-bit Media Player.  This issue seems to only effect 2 Channel stereo SD recorded shows using the "MPEG Audio Decoder".

Any thoughts?

I also found out that if I force todvrms.exe to run as a 32-bit process with the following command:

corflags todvrms.exe /32BIT+

I get the following results:

DVR-MS crashes Media Center (64-bit) ***
DVR-MS crashes Media Player (64-bit) ***
DVR-MS also crashes 64-bit Graphedit

Although

DVR-MS plays fine in Media Player (32-bit)

Just to bump this thread, I've tried recording some stuff off BBCHD with the beta-fixed .dll file off DVB-S..

It plays fine as a .wtv, but is there anyway I can extract/convert the h264 out of the container?

Go here and ask to be added to the Beta. MCE Buddy now has support for .wtv and will extract to TONS of different formats. Since it is Beta, not all of the formats are available, but they definitely work with .wtv in version 2.08a.

Wow it worked, got a test wtv file converted to dvr-ms =]

Awesome, finnally something today has gone right!

Many Thanks

I've been trying to make a simple app using visual studio express to do this without much success. However, after playing around with graphedit I have found something that may be useful for people with ATI hardware (I'm not sure if my ATI Theatre 650 installed these filters, or my HD3200).

This graph takes the mpeg streams from the source .wtv file and remuxes them into a new mpeg file. I haven't tried the resulting file with any software other than VLC and WindowsMediaPlayer11 yet.

note: The audio and video pins change depending on the source recording

1. Graph->Insert Filters->DiectShow Filters->StreamBufferSource. Select source file.
    Graph->Insert Filters->DiectShow Filters->ATI MPEG Multiplexer
    Graph->Insert Filters->DiectShow Filters->ATI MPEG File Writer. Select output file.

2. Right-Click on each pin from the StreamBufferSource and select "Render Pin" until the 1 audio and 1 video pin are connected to the ATI MPEG Multiplexer. The other connections will be made automatically.

3. Delete any filters that may be connected to any pins that are not your uadio and video pins (in case you rendered any extra pins while trying to find the audio and video pins).

4. Click on the "Play" button.

On my machine this created a new file very quickly (3 min for a 1 1/2 hour hd recording). No processing or transcoding going on, just repackaging the A/V data.

I hope this can help put some people on the right track.

I've been successful with the beta of MCEBuddy.  Nice program.  Takes some time though but I expect to see some improvements soon.

with MCEBuddy, can you convert WTV files to DVR-MS and then remove commercials? Or can it remove them directly from the WTV files? It seems unclear on their website.

There is a new trial of PowerDirector 7 at Cyberlink which supports (or so says) .wtv files.

For me it didn't work. The progress bar was stuck then eventually PowerDirector crashed. I was left with a 110mb mpeg file with no sound. I think the problem (which i'm having whatever I use to convert) is the UK Freeview DVB-T transport stream. It is made up of  Video, 1x Stereo audio, 1x mono audio (Visually Impaired) & Subtitle. I think it's because there is 2 audio channels it doesn't know which to pick. With other Apps they seem to go for the mono channel thus giving the impression of no sound or a voice filling the gaps when no commentry would be going on in the stereo channel. For me the perfect solution would to demux the whole transport stream to it's bare parts as ProjectX can do but ofcourse ProjectX doesn't support .wtv.

Hope the rest of you have better luck.

Wow, this works like a charm. Is there a way to automate this?

Hi!!

 

Can someone tell me if I can also convert any file INTO wtv?? Like doing it the other way around?

I want to be able to add subtitles, audio track and video track to a wtv file.

 

kind regards
