NPVR unable to play GBPVR .mpg recordings

[chunkymonkey909]

I have been happly using GBPVR for quite some time but decided it was time to take the plunge and upgrade to NPVR.
All has gone well except I am unable to play the imported recordings. They are all listed under recordings but when I select play I get not sound or video. I can play them with Windows Media Player. They have a .mpg file format and were recorded with GBPVR from a DVB-T source. I think they would have normally had a .ts format but I enabled 'BDA Multiplex = Cyberlink" to save them as .mpg so I could access them from other PC's etc.
I'm using Windows Vista and have tried MS MPEG and FFDSHOW decoders.
A previous simular post on this forum suggested install Haali Media Splitter which I have done but it did not make any difference.

Thanks

Have you configured the audio and video decoders to use on the Decoders tab of the settings?

Have you installed a mpeg demuxer?

[chunkymonkey909]

@McBainUK I have tried ffdshow and MS MPEG2 video decoders.

@Reddwarf I must have installed a demuxer when I first installed GBPVR but since I have installed NPVR i have not installed another. Do I need to install one or can I register the Cyberlink one (if thats a demuxer) that was installed ages ago in NPVR? I did'nt see any demuxer option in the NPVR settings.

I have just reran the Registerfilters option in NPVR programs and got the following:-
NPVRCCDump.ax succeeded
NPVRPEScollector.ax succeeded
NPVRTSMon.ax succeeded
NPVRWriter.ax succeeded
NPVRTSReader2.ax succeeded
NPVRMP3Reader.ax succeeded

But still no joy.

My logs show a "MPEG-2 Demultiplexer" in use playing an mpeg in NPVR. Not 100% sure which one that is. If I use graphstudio, then it builds the graph with the LAV Splitter. Either way, mpegs are playing fine for me in NPVR.

The filename is mpg2splt.ax, but I don't know where it comes from.

Ok, found mpg2splt.ax in \windows\system32 and reregistered it but no difference.
Thanks for all the suggestions so far.
Part of the problem is i don't understand how decoders and demuxers work. I am very impressed with how NPVR handles the tuner cards now - so much easier to setup than gbpvr. Just wish decoders/demuxers were so simple in windows :-)

I had to play about with a couple of settings in config...

Code:

<ForceMpgGraph>false</ForceMpgGraph>
    <MpgUsingSplitter>true</MpgUsingSplitter>

Try what Alex says above. Quite a few people need to do this to get .mpg files to play correctly.

<ForceMpgGraph>false</ForceMpgGraph>
    <MpgUsingSplitter>true</MpgUsingSplitter>

I have both of those set the other way around, i.e., true, false in that order (presumably still at their defaults as I don't ever remember tweaking them).

I'm on XP SP3 using VMR9 and the MPV Video Decoder and MPA Audio Decoder and old GB-PVR .mpg recordings play fine for me.

mpg2splt.ax is a default MS directshow filter (in XP at least, not sure about Vista/Win7) and actually exposes both the "MPEG-2 Demultiplexer" and "MPEG-2 Splitter" modes.
