I have some problems using MyTv. From time to time TV will crash and I get a black screen and not able to watch tv (need to restart computer). I have not seen any patterns when this happens and it can run for some time without any problems, but on other occasions it will crash after 10 minutes or less. This is both when just watching TV or recording.

The errors I get is:

"DVBGraph: FAILED unable to start graph :0x80070079"

usually followed by

"DVBGraph:FAILED cannot add StreamBufferSink:4022D"

and other errors related to timeshift. (however the error log file supplied only had the first error this time, but this probably has to do with this time I didn't try to switch channel after first crash".


I am running WIn XP SP2, I have used both the MS DVB patch and the later patch for MCE (those patches mentioned in the requirements). I had this crash bothe before and after I have installed the patches.

Also using "Terratec Home Cinema" works fine. Never crashed so far.

Signal strength and quality is good (95-100% signal strength and 100% quality).

I am using the "MPV decoder.

The Terratec supplied software is using "Terratec Video Decoder" (can use MPV there as well but hadn't crashed so far, but have not run with it that long though). That filter does not show up in MP setup btw (is it possible to use it in MP? In Terratec Home cinema it looks better than MPV decoder).

Any ideas what to do ?

forget the Signal strength and quality values, they are completely wrong because the driver doesnt supply valid values.

if it is still crashing with both patches installed, then it must be something else. but i have no clue what. :s
its very weird that it crashes after some time. and not instantly...... never seen such.

I have a feeling that it is related to channel switching. I think it has always crashed when switching from one channel to another. Going to test this now by keeping the same channel running and see if it is stable

Not sure how to troubleshoot this. What does the error message really mean?

I watched (well had it running in the background) same channel for a n hour or two without any problems. No hangs, stuttering or anything. TV was looking great.

After that I started to switch channels. I noticed some slow channel changing and sometimes a channel would show a black screen (swiutching back and forth would show the channel, but for some channels it took several attempts). I turned off time shift and those problems disappeared.

I zapped around for 20 minutes or so maybe then switching from mini-epg (ok button) resulted in tv stop responding and mini-epg remained on-screen. I could switch to home screen etc but mini-epg was still on screen. Finally the mini-epg wnt away and MP was again responsive but TV not working. When trying to turn on TV I get DVBGRAPH errors.

I also noticed memory use increasing when running MP. It started at 45 MB and so and increased up to 130-140 MB.

this issues was fixed last week as far as i can remember.

you should apply the latest svn build or wait for the 0.2.3.0 RC2 (wich will be released very soon )

You mean this fix?

"01/09/2007 [01:10h] gibman added: fixed miniEPG was not closed immidiately when changing channel fullscreen. also somestimes miniEPG would not disappear. channel change fullscreen is now a bit faster"

Don't think it what is causing my tv crashes though. I had tv hanging without leaving mini-epg. But it is good that it is fixed though (one of those small glitches that make WAF drop fast lol).

Guess I need to try a new clean setup and see if it helps. Possibly also testing with TVE3.
