Resolution Change Stops Video Playback (1 Viewer)

[mizzourob]

Let me start with a disclaimer that I'm not sure if this belongs here or in the MediaPortal help section on the forum as this perhaps borders on both it and TV-Server.

I've noticed a bizarre problem when my local cable company inserts local commercials into the cable feed, they change the image size from 1920x1088 (which TV Server cuts to 1920X1080) to 1280x720 based on what I can understand from the TSReader.log file. When it changes to the smaller image a gray bar resembling the old Windows 98 taskbar appears below the image several pixels (8?) tall. Then after the local commercials are over the audio continues ok, but the display turns black. Seemingly indicating a problem with switching resolutions back to 1920x1088/1080. If I timeshift back several minutes before the commercials, then timeshift forward past the commercials I can avoid the issues.

I'm running MP version 1.0.0 on a Windows XP Pro machine

Here are the relevant log entries:

Thanks so much for such a great product!

If it would help I could upload a videoclip but I don't want to run afoul of copyright laws on re-posting of content

 

[scma]

this is most likely a decoder problem, try changing your mpeg2 decoder to cyberlinks

I've tried the PowerDVD and still no luck in preventing the black screen yet

Hi,
Need full logs for this one & ffdshow for video it's not recommended(at-least for now).

Solution

Well it seems I finally found a solution, though I can't say with 100% certainty which part of the following fixed this problem of it it was a combination of the following:

1) Clean install Windows XP
2) Install MP 1.0.1
3) Remove all other codecs (including FFDShow) and install the Standalone Filters for MediaPortal (including the CLVsd.ax hack)
4) Add DirectVobSub as a TV post processor (my feeling is that this is the prime suspect for fixing the problem)

voila the broken video stream problem is gone!

So does this render daMaster's Most Excellent Guide wanting for revision?

I am pretty sure I have entered codec hell__
