Can't fast forward

[march]

Guys, i know this probably belongs in the wd live web site, but was wandering if anyone has experienced the same and had a fix. All this through the wd live product. The programs are recorded using NPVR.

Hi , I record all my tv shows. I'm having problems at the moment where you go to fast forward and after 5 seconds it goes back to the beginning. This is very frustrating. I recorded gladiator last night and tried the fast forward and it worked where i fast forward and press play and it plays from where i say to play. But on the shorter shows of 1/2 an hour or so it dosen't seem to fast forward successfully, but stops after 5 seconds and goes back to the beginning. it sometimes maybe be longer. Can anyone help.

Since you're using WD Live for playback, and just playing files, it must be some limitation or bug in the WD software. I'm not sure if they have a support site where you can report bugs, and hopefully get fixes? Sorry, I know thats not super helpful, but in this scenario NPVR doesnt play any part in the problem. It's likely that the WD just isnt very good at coping with clock discontinuities that you get in broadcast streams.

Thanks Admin, your right, its not a npvr problem. will keep looking

Forget this. You will never win! Sorry to disillusion you, but it seems that this is an inherent problem with TS files, which only the great magician sub has been able to circumvent in NPVR. Even VLC cant do it properly.

I gave up trying and post-process all my TS files with FFMPEG.
My current, most successful, conversion is:

Code:

%FFMPEG% -y -async 48000 -i %1 -vcodec copy -acodec copy -threads 16 -sameq -ac 2 %VERBOSE% %CONVERTED% >> %LOG% 2>&1

This fails sometimes with an error about non-increasing timestamps.

I have heard rumours of non-standard firmware for the WD, but have not tried it.

Good luck.

Oops.

CONVERTED is set to %1.avi

I think i know what is going on. there was a file created every time i recorded called a .ts.Timing.Info file. When connected to the wd live this gets created. On my other hard drive that was connected to wd, i disconnected and connected to my pc, so the drive was shared. the timing info still gets created on this drive, but it is nearly full. but i bought a new hard drive and connected it to the wd then reconnected to the pc and the timing files don't get created. don't know how it worked on the other on. Does anyone know if this comes from the wd live player or npvr, i would say the wd live. anyway, i think that is the baSIC PROBLEM, THE TIMING FILE ISN'T BEING CREATED NOW whenever i record a new show. With this file the operation was flawless. an example of one is when i recorded freinds : Friends_20110718_10301100.ts.Timing . again all the recordings happen from npvr.

the Timing.Info file is created by NPVR, and is only used by NPVR. The WD live doesn't use it so it won't help for playback on the WD.

if the drive is formatted NTFS, the Timing.Info gets created as an Alternate Data Stream (ADS) within the .ts file itself (do a 'dir /r' in a directory of shows recorded by NVPR, and you'll see the Timing.Info and metadata.xml ADS's on every .ts file). if the drive is formatted some other way which doesn't support ADS (fat32 or some sort of linux-based NAS box), NPVR now creates the Timing.Info file as a separate file. I don't know of any condition now where NPVR won't create the Timing.Info one way or the other.

Without use of the Timing.Info, some .ts files play better than others. This is likely what you're seeing where it works better sometimes than others on the WD Live.

Very interesting. I didn't know that. so when the drive is connected through the wd live it creates the file ( i have found it performs better with this file ) when i connect to the pc the file isn't created. I may format the drive to ntfs, i think it already is but will check

the Timing.Info file is created by NPVR, and is only used by NPVR. The WD live doesn't use it so it won't help for playback on the WD.

It is used by mvpmcx2 too for playback on the NMT. Incidentally march you could have bought a Popcornhour and it would have enhanced you extender playback with the complete NextPVR interface.

I don't know of any condition now where NPVR won't create the Timing.Info one way or the other.

It isn't used on LiveTV or for viewing Recordings in progress.

Nor is it used on pc-clients, according to Sub.
