Cannot Play All ATSC OTA recordings

[donovan_ict]

I am not sure if my problem is a configuration issue, codec, hardware, or signal issue. I've looked up and down the forums, and used the fixes in the survival guide.
When (my wife) plays certain shows, they intermittantly jump into fast forward mode, or stop playing.

I just upgraded to a new system in Jan. for the ATSC conversion, and now it's intermittant.

After purchasing a better video card, ATI HD3450, I can playback with little CPU usage most shows. Even the shows which fault have low resource use. I've got a 2.5Ghz, 768MB RAM, and XP, and it worked excellent in the analog realm.

I've posted my log folder, maybe something can be decoded from it. I've also tried to playback the faulted recordings in WinTV, VLC, and WMPclassic, and all fail. I've tried all different playback codecs and none work when the fault occurs.

Maybe I could post a segment of the latest video to megaupload with the fault? Right now it's a 92 min 13.451GB TS file, which first faults at the 3:00 minute mark. I'm not sure how much to cutchunk to get a good sample, or how to parse this file and check it for (signal) errors.

Thank you.

looks like youre using the Full TS Mux.. try changing the mux and you will probably fix the issue. I've never had success with the TS Mux or with DVR-MS.. CyberLink mux can lose a/v sync on some HD stuff, ATI Mux works perfectly with everything. I'm also using a HVR-1600.

I have the same problems. I tend to think it's a small glitch in the signal, which confuses the playback process and results in a jump to fast-forward playback. I've had some cases where if I don't hit pause a few times to get it to stop, it will fast-forward all the way to the end of the show. I've confirmed the glitch is just at one place in the file, because if I go back to before the glitch, and then skip over the corruption the rest of the file will play back fine (or likewise, once I get it to stop racing through the file, I can skip back to just after the glitch and resume watching without incident).

I've been trying to find an example small enough to to cut a chunk and upload for sub, but it always happens a good ways in to the show and the cutchunk utility takes only the first xx megabytes (unless there's something I don't know).

For your file, if you cut about 600MB (still huge I know), it should include the glitch and a minute or so after it to prove the rest of the file is fine.

I just logged on to find out the answer to this same problem. Did a bit of looking and found this this. Would it fix the problem? I have to wait to try it.

[gemmagirl]

Never mind. I already installed it. Tried it again just in case - still have the same problems.... don't mind me.

Automatic fast forward is one of the symptoms that I get when I record to .ts files. I have no doubt that this is due to glitches in the signal.

Recording to .dvr-ms handles these glitches much better.

Good Luck

sgilani, your signture sounds like you're using a similar setup to me. What playback MUX do you use with you ATI mux? the ATI?

I think I've tried that before and come across similar issues.

If I do have a glitch in my TS file, is there anyway to play it back in some "Safe Mode" where it throws out errors? My wife really wants to watch the dancing with the stars show.

I'm posting to megaupload a segment which < should > hold my glitch.
I took the original recording, 13,451MB, divided by length 92 min = 146MB/min.Then cut the first 4 minutes = 500mb, then cut from that, the trailing 1.5 minute so should... have a big 200mb file... with the glitch that caused my playback to jump into fast forward.

I dont know if the section is playable, if it is, the glitch happens when the very first group begins to dance.

Well, it looks like the upload will take some time, I'll post the megaupload address after work today.

I didn't see in this thread if you tried dvr-ms or not. From past experience and problems, if you don't have a particular reason to use .ts (possibly glitchy) or .mpg (possibly out of sync), use dvr-ms.

For me, different versions of Cyberlink all would cause out of sync, and ATI Mux would often work but then out of nowhere would destroy the audio of a show. DVR-ms, perfect.

I hope this file has the evidence of why my playback ( logged previously ) went into fast forward. http://www.megaupload.com/?d=CCTI49W0
