Problem: I am unable to play files w/ the .tp extension via MP, while the same exact files with the extension changed to .ts play fine.

I used to be able to play .tp files with no problem, but recently rebuilt my system and they are no longer playing. I have added .tp as a recognized video file type, and MP recognizes/displays the files just fine.

I've attached the appropriate log files as required, and they exhibit the following error when attempting to play a .tp file:

VideoPlayer:exception while creating DShow graph A dynamic link library (DLL) initialization routine failed. (Exception from HRESULT: 0x8007045A) at System.Runtime.InteropServices.Marshal.ThrowExcept ionForHRInternal(Int32 errorCode, IntPtr errorInfo) at MediaPortal.Player.VideoPlayerVMR7.GetInterfaces()

If I change the extension of one of these files to .ts, it plays just fine, so it's not the files.

The .tp files play fine in VLC and WMP.

Interestingly, running GraphEdit against the .tp file shows the following:

file -> SnapStream TS Demultiplexer -> NVIDIA Video Decoder & AC3Filter

GraphEdit against the same file, renamed to .st shows this:

file -> NVIDIA Transport Demux -> NVIDIA Video Decoder & NVIDIA Audio Decoder

MP is configured to use the Nvidia decoders for both video and audio.

I'm at a bit of a loss at this point. I've removed and reinstalled the nVidia PureVideo package to ensure it's registered properly, but that has made no difference. I would just rename all my media to .ts and this wouldn't be an issue, but I have quite a bit of media I've burned to DVD's w/ the .tp extension, so I'd really like to get the files playing properly via MP. Additionally, I'm actually use BeyondTV for my TV functionality at the moment, and it's recordings are written as .tp.

Thanks in advance for any advice or suggestions. Also, if there is any further information or clarification necessary, please let me know - I'll provide whatever I can.

Thanks!

I would like to see this fixed too because I also use BTV for TV services and would like the option to play them back in MP.

Well, as you probably noticed, no other replies to this thread.

Though I have not yet found a fix, I do know what in particular is causing the issue.

The problem is w/ BTV 4.5. Rollback to 4.4 and you'll be able to play the files fine in MP.

My guess is that there is some problem w/ the way the BTV 4.5 install is registering the SnapStream codec; BTV will use it fine (I think it accesses it directly), but MP throws an error and is unable to properly use the it (I believe it is attempting to use it via dshow).

I haven't had any luck fiddling w/ dshow codec preferences/weights trying to force MP to use a different codec. But I can confirm rolling back to 4.4 will fix it. With any luck, maybe the next BTV update/patch will fix it.

Cheers,

Chris

I had already rolled back to 4.4 because of the jerky playback problems of 4.5. I tried it again and it worked, but playback wasn't very smooth using the snapstream codecs in MP. I played the same file in VLC and it worked perfectly.

Not sure if it'll make any difference for you or not, but I'm using purevideo and I've got perfect 1080 playback in both MP and BTV.

I think the problem with the different versions of BTV is actually a dumuxer codec. Can't remember exactly what graphedit shows for ts files on my system, but I seem to recall for .tp files, they always hit the SnapStream dumxer, though the video/audo do get decoded by purevideo...

Do you see any difference in playback between .ts and .tp in MP? If so, you might attach graphedit to the running graphs to see what the differences are...

I am having this problem as well. I do have BTV 4.6 installed, but I'd like to manage my library with MediaPortal. Renaming the file from .tp to .ts works, but I'd like to keep .tp so it can be viewed in either application.

Edit: I looked at filtergraph and .ts went to haali and .tp went through snapstream. I downloaded hdtvpump and verified the filter graphs looked exactly the same for both .ts and .tp files, but the .tp file still would not play.

Edit 2: Success! I found that I could bring up the properties of hdtvpump inside the filter graph. In the dialog is has a box that allow me to specify .ts and .tp files and it also allowed me to specify my preferred demuxer. I chose the NVIDIA demuxer. I can now play .ts and .tp files through MediaPortal.

Guys - quick question. Can you tell me how you set up MP to access the BTV recordings? Would like to playback my recordings in MP.

Thanks.
