Upgrade to 1.4.7 – PVRX2 crashes when playing recordings

[Deev8]

I’ve updated an old rarely used Vista 32 based PC that has been happily running GB-PVR version 1.0.16 since it was released, and I've run into a problem.

In preparation for installing version 1.4.7, I downloaded and installed the new version of the Visual C++ redistributable that sub linked to in the “1.4.7 available” announcement thread. That appeared to install correctly, with Event Viewer reporting:

Windows Installer installed the product. Product Name: Microsoft Visual C++ 2005 Redistributable. Product Version: 8.0.59193. Product Language: 0. Installation success or error status: 0.

I then closed the GB-PVR Tray app, stopped the recording service and ran the GB-PVR 1.4.7 installation. Again that seemed to be OK and Event Viewer reported:

Installation operation completed successfully.
Windows Installer installed the product. Product Name: GB-PVR. Product Version: 1.4.7. Product Language: 1033. Installation success or error status: 0.

A lot of GB-PVR functions seem to work without any problem – Music Library plays mp3 files OK, and Video Library plays Xvid avi files just fine. Live TV from an analogue tuner works, and I’ve successfully scheduled a recording from an analogue source. Recordings which are all MPEG-2, both pre- and post-dating the version upgrade can be played by Media Player Classic or Windows Media Player on the same PC. When exported to my main HTPC, GB-PVR version 1.3.11 also plays them without any problem. However any attempt to play a recording on the new version 1.4.7 installation results in PVRX2 crashing:

PVRX2 has stopped working

You'll need to reproduce the problem, then post the logs.

Thanks sub - I've reproduced the problem and the logs are attached, but I don't think they provide much to work with.

About to play file: J:\TV Recordings\New Zealand On A Plate_20090919_17251800.mpg is followed by nothing - which is where I get "PVRX2 has stopped working".

Unfortunately there isnt any obvious cause of this problem shown in the logs.

If you download and run GraphEdit, and select the 'render media file' menu option, then choose your .mpg file, what happens? This will often tell you an error which will pinpoint the problem GB-PVR is having.

The graph shows the Ligos MPEG Video Decoder being used. I have the Intervideo NonCSS Video Decoder for Hauppauge selected for MPEG-2 playback in GB-PVR config, however if I select the Ligos MPEG Video Decoder instead I get the same result - PVRX2 has stopped working", and nothing different in the logs.

I'm guessing the Ligos MPEG Splitter is causing the problem. This Ligos software seems to have taken over the job that would normally be performed by the Microsoft MPEG2 components.

It may have been a guess, but it seems to have been a very good guess.

As a test I unregistered the Ligos MPEG Splitter, rendered one of my recordings again in Graphstudio and saw that the Microsoft MPEG Demultiplexer was selected in its place. Sure enough GB-PVR now plays the MPEG-2 recordings without a hitch.

I may have to resolve unwanted consequences of removing the Ligos splitter later - other applications that may insist on using it - but that's a minor concern compared to a fully functioning GB-PVR.

Thanks very much sub.
