Odd thing this, i have working recordings from GBPVR (can play them on VLC and working in the UK with a UK MVP (PAL) recorded from a PAL PVR USB2 unit.

However i now have a USA MVP (NTSC) which wont play the UK recorded programs, the MVP works as have other files that it will play.

Will the MVP only play there native (NTSC / PAL) formatted MPEG files?

The Hauppauge dongle reject PAL NTSC mismatches. mvpmc will play them but the bottom is cutoff. Modern extenders like the NMT have no trouble scaling PAL (or HD for that matter) to NTSC SD.

Playing with it now.... did wonder if it would be a size mis-match.

Using this one http://www.mvpmc.org/~mvallevand/dongle.zip, doesnt seem to be playing PAL MPEG 2 files on my NTSC MVP (recorded in GBPVR that played on a UK MVP)... Play on file results in black screen for 3 seconds then the menu.

The same files with VLC play fine (as expected) on a PC.

Post a 10 Mb sample on megaupload and I will have a look the next time I boot an MVP

Unable to cut down a file without re-encoding it... however here is an output data for the codec used to encrypt the file (that wont play on the NTSC MVP but does play on the PAL MVP).

File : 3.94 GB (1.42 GB), duration: 2:21:58, type: MPG, 1 audio stream(s), quality: 75 %
Video : 1.20 GB, 5250 Kbps, 25.0 fps, 720*576 (4:3), MPG2 = MPEG 2 (SVCD/DVD)
Audio : 227 MB, 224 Kbps, 48000 Hz, 2 channels, 0x51 = Mpeg-1 audio Layer 2 [0xc0]

That wouldn't be the same test. I wanted to try a file that was known to not work on your system. Any binary cut would have worked.

The experience with the truncated PAL files isn't great anyway. Just rename them to avi and let ffmpeg do the conversion for you.

Found a splitter, there is a 100Mb file here, this still works on VLC on my desktop and still has the same codecs inplace used (so hasnt altered the file).

As expected, your test file played on my NTSC monitor using mvpmc, cutoff at the bottom with green pixelization.

You are using an MVP. I thought it just played everything with no configuration.

Assuming the file is MPEG2 yes, however the orginal question was there seems to be a difference between PAL and NTSC sized MPG2 files.... slighty confused here as you asked for the cut down file... now your saying there shouldnt be an issue...

so which log file do i look for to track down an issue

I am just making the comment that if your read the posts, everything seems a lot more complicated.
You have two possible problem, you either didn't load mvpmc properly, or the file is stored on a share that the MVP cannot access. I always like to get all the logs.

Not possible, the MVP pulls this, the MVP also plays others files without issues and shows menus, the only way that would be possible is for a corrupt BIN file in the DONGLE directory, and as i can view the weather meaning its loading it fine.


or the file is stored on a share that the MVP cannot access

The MVP doesnt use shares, GBPVR sends i directly, again works with other files in the same directory..

Sorry I meant PVRx2 running as an MVP server. Anyway I will await your logs.

any reason why you dont want a specific log when you know which one you need?

Yes I have a good reason. I don't want to waste time explaining which logs I want.

dont worry about it, i've asked Hauppauge directly so you dont need to spend time on it...
