Hanging problem

[Paulp33]

Having sorted out my aspect ratio problem I ran into another one. I was playing a file and when FF was pressed the screen went black with the stop symbol showing in the top right of the screen. A bit of playing around found it would only respond to two keys. If I restart it with the power key it can't refind the server until I restart it on the host computer. The other key was the "OK" key. When this was pressed it restarted another file at which point I could carry on as normal. The file that restarts appears to be whichever was the first file that was played when the MVP was restarted. Sometimes the file that restarts just goes straight to the black screen as well which necessitates a restart of the server. I am not sure if FF is the only command that prompts this. It also seems to relate to the files selected, I found one file that would do it every time but other files would be fine.

Here is a section of the exe log

I just read in a wishlist thread your comment that the recording service now acts as the MVP service. I have been starting the mediaMVP service via the start menu (generates the popup that minimises to the taskbar). Could this be causing any problems?

No, I dont think so.

Just so you know, you can start it as a service by editing the 'number of servers to autostart' option in the config app.

I made the automatic severs 1 and stopped manually starting it. The problem is still there but now it usually restarts the MVP rather than hanging on the black screen.

After playing around with different files I think I have narrowed the problem down to captures from specific TV stations. The one thing that stands out about these two stations is that they transmit 18 frame GOPs (they are DVB-T) whereas the other stations transmit 15 frame GOPs. Seeing as 15 GOPs is the standard for DVD could this be causing the problem?

Possibly. If you have access to a web server, and chance you could make a small video file available to me?

[Paulp33]

Unfortunately I don't have access to a webserver but i can probably email you a few Mb (I think we can send up to about 4 or 5 Mb before the system spits the dummy).

Yeah, give it a go - support@devnz.com

[Paulp33]

OK, I'll probably send it on Monday.
