Problems with .ts playback in nPVR

[ShiningDragon]

After some days of intensive testing (watching live tv, recording, playback recordings/movies etc. via lan) i experienced a few problems (using nPVR with all available hotfixes and original 1.5.33 tsreader.ax):

• Watching Live TV on a nPVR Client is bad and asynchronity follows
This is nothing new and well known by nPVR Client users.

• Watching .ts recordings via nPVR show a similary behaviour like watching live tv (sound and video get's asynchronous, not as bad like live tv, but annoying enough).

• Skipping while playback a .ts is desastrous. Sometimes it's working (then i have to wait up to 2 minutes till video playback the skipped part!) or nPVR just freezes.

• If i playback the same file within Windows Media Player, then nearly all is fine. Pointing to timecode ABC, video plays back fine after ABC. Pointing to XYZ, video plays back fine after XYZ. Zero seconds to wait, instantly skip!

• If i open a .ts file created by nPVR and use vlc for playback this video, then i'll get some points in this file, where i have distortion in the picture (the same distortion people get, if the receipt digital tv and have low quality); but the recorded shows are from analog(!) tv.

Something is not right, either with the generated .ts files, or with the ts reader/writer.

If you have any idea how i could supply you with more information for bugfixing, then just asks. The logfiles tells nothing special at the moment.

Btw., playing back videos from videolibrary works like a charme.


EDIT: As an idea... would it be wise to install the hauppauge! mux, which is installed on the nPVR server on the nPVR clients too? Could this change anything in playback .ts streams?

I needed this patch http://forums.gbpvr.com//showthread.php?...post394203 to fix a/v sync issues in .33 I suspect it is needed on the client too.

Do you mean the patch in post#48? I tried the last patch in the thread and had similar problems as SD describes here. Playing back a recording the sound was sometimes way ahead of the picture and after a jump it was sevral seconds behind the picture.

I've also noticed that it streams a SDTV .ts file it uses an HDTV bandwidth which is nearly 3 times as high as an SDTV .ts stream should be. Play back the same file from the client using a file share and the transfer uses the expected amount of bandwidth. A glitch in this part of the program and not the database could also be a cause of some of the odd and unreliable scheduled recording. Right now to watch live TV on my client I increased the buffer to 2 hours and then right click from the main screen and chose open file from the pop up and point it to the live tv buffer and grab the stream as a file share, then I can skip ahead and be just a few milliseconds behind the actual live signal (Makes a neat echo/cave effect if you have the server and client both going in the same room) but that means I have to go to the server to change the channel and then rehook to the new file in the live tv buffer. I'm not ready to commit to any serious Series recordings until this is worked out so I have to alternately disable and enable NPVR and Windows Media Center for now. Luckily I'm only recording two series so I only have to make sure I switch over two nights a week.

Another thing is the client is finicky if it doesn't have a server connection so I have to disable it on the clientmachine if I'm mobile or I have the server machine turned off or disabled for recording in Media Center.

Thank you Martin, i tried this patch 2 hours ago and tested different situations... but no luck. This time i captured a "live tv" stream. On the left side played back with vlc (it can access open files) and on the right side npvr. My digicam can capture only 59 seconds of video, so i started capturing after 2 minutes.
As i started to playback on both mediaplayers, the video were synchron on both sides! See yourself that something is going badly wrong...

EDIT:
And this happens, if the osd appears while playback a .ts file.
