Previously I was using the 17150.

I've tested the 17383, it's not working with all TV channels with PMT greater than 188 bytes ( may be due to Cyberlink codec, seems a little bit better with MPV, but not sure ).

I've now loaded this new build that should fix the problem, and now TvService crash on all these channels !!

Memory used by TvSevice normally around 25Mb increase suddenly to more than 100Mb and disappear from the task manager. ( No crash window, no blue screen..... )

I attach the Tv and TsWriter log files

Another thing concerning MPA decoder ( but I don't wher it comes from ), single audio channel MPEG2 ( mono ) is not working and freezes the video !

Regards.

Anyone got any screenshots of a 16:9 skin runnig PIP or PAP with TVe3??

Anyone got any screenshots of a 16:9 skin runnig PIP or PAP with TVe3??

MediaPortal does not support either of these, However MP2 does when it is released.

Hi,

It seems a part of the problem is in the DiskRecorder.cpp.
On CANALSAT in france, we receive PMT up to 431 bytes ( may be more ), and the function below will crash on the red lines.

I've attached a log from 17383 where PMT error size appear.

Ok, too bad. When is MP2 released?

I can no longer scan for channels using DVB-C.
Only channels on the first transponder is found. After that all remaining transponders says Nothing found. At this point the TV Server crash almost every time. In tv.log i see that 8 channels is found on the first transponder and 11 on the second however only the first 8 channels is visible at TV Channels.

In error.log:
System.AccessViolationException: Attempted to read or write protected memory

In SVN 17305 I could complete a scan but no HD channels were found.
In SVN 17267 scanning is complete and all channels found.
