So I re-associated the file to the PVR program but nothing happens when I open it...


You don't want .asp files associated with the PVR. You want .tvpi file types associated with it. But then when you run the PVR it should notify you that one or more of the required associations have been lost and offer to get them back. Exit the program and restart it. Respond OK if you see the associations dialog. With XP/2K you shouldn't have to restart for the registry changes to take effect.

Ok... reinstalled and now it seems that the tvpi files are associated with the PVR. However.... whenever I click on a REC button, I get a popup error box which says:

Error. Couldn't parse file! (exclaimation point in original... not added by me.. )

Again... this is on my client box which shows a connection to the server.

TIA!

While experimenting, I have run across an odd issue with the PVR beta:

If I hit record for HBOHD (channel 9456), a percentage of the time it instead records channel 9467.

Anyone else getting similar channel mixups?

Finding that many of my recordings can't be played unless I run them through mpeg2repair. If I try and play them prior to running them through mpeg2repair, the video does not show up and the audio sounds like it is in fast-forward mode. After running them through mpeg2repair, they work like a champ. Seeking and all.

BTW, for playback, I have been using Zoomplayer, with HDTV Pump, NVIDIA DVD Decoders, and AC3Filter .

I downloaded the 2 SDTV clips from this page:

http://www.nextcomwireless.com/R5000/samples.htm

Are these clips re-encoded from the original DishNetwork/DirecTV signals? Or are they the native files that DishNetwork and DirecTV use? In other words, are you just capturing the native stream that satellite providers send bit-for-bit and saving it on a PC? Or are you converting it from the proprietary formats used by DishNetwork/DirecTV so the resultant file is fully-compliant MPEG-2 that has broad compatibility. I read some information on the R5000 but still wasn't sure.

No. They are not re-encoded.

Yes, All the original bits are preserved, but No, you can't use the stream directly.

Yes, format conversion is done to ensure the resulting stream is fully-compliant.

Thanks.

I'm having some trouble playing the clips. The players I'm using report different clips lengths. One video continues playing when the time bar reaches the end. The other clip won't play to the end.

How long exactly are the clips in minutes and seconds?
post #338 of 2773
I get 36 sec for the first one and 1 min. 33 sec. for the second one. John
post #339 of 2773
I just thought I would chime in to say that since the release of the R5000-HD Beta 2 software, I have had virtually 100% perfect recordings to disk with no Failed Transfers and no "Data Loss" using my Dish 6000-R5000-HD STB.

Can anyone confirm that E* is delivering a more constant HD bit stream lately?
post #340 of 2773
I use to edit the movies recorded with my Dish 6000-R5000-HD STB like taking off the nudity scenes, I'm using HDTVtoMPEG2 software the problem that I'm having when playback the video is for some cuts the video freezes for few seconds before it jumps to the next portion of the video, Can somebody give me a technical explanation? Thanks
post #341 of 2773
It's just that HDTVtoMPEG2 is cutting and splicing in the simplist way possible: chopping transport streams without regard to the video and audio structure. Your player apparently doesn't like the discontinuities that it finds at the splice points. Other players do a better job.
post #342 of 2773
balazer is correct. HDTVtoMPEG2 is a great little tool but it was never meant to be the end all of editing.

There is a time code running continually in the .ts file. When you edit a piece out, that time code is broken and a piece is missing. To borrow a line from a movie, thiink of it as a prolbem in the space-time continuum.

But, to your question, many players do not like that missing chunk of time and don't know exactly what to do so they stop and try and figure out how much is missing and what to do next - to put it in oversimplistic terms.

You could try another player - or assorted players until you find one that might work a little smoother.

You could also try mpeg2repair to try and see if that smooth it out - most likely you will still get a lock up - only shorter in length.

The only real way around it as I understand it is to demux and remux the stream to reclock the stream.
post #343 of 2773
VideoReDo is an alternative editing tool that will produce output without discontinuities.
post #344 of 2773
Agreed, but until the version is released that produces a .ts output instead of .mpeg, that is often harder on software players than the discontinuties.
post #345 of 2773
I thought the beta produces transport stream output.
post #346 of 2773
You're all right I was using VLC media player and just tried Moonlight it plays smoothly however the picture is not as sharp as on VLC beside that it's not free, is there any other player has the quality of VLC for .TS playback ?

I know it can read .ts, but last I heard it would only save to mpeg and elementals for muxing to .ts with another program.

It's clearly in the works and will be the frame accurate editor of choice this year once its done.
post #348 of 2773
VideoReDo is not designed for HDTV .TS files I tried it and it won't open the file. Probably small MPEG video files works with it like home videos.

post #349 of 2773
Yeah, well I heard that they have a beta that works with HDTV transport stream files.
post #350 of 2773
Yes that's what I tried beta version, maybe the video has to be MPEG2 not .TS to be accepted, Any way my problem is with playback and I couldn't find a .ts file player that has the good picture quality like VLC media Player.
post #351 of 2773
The beta will open .ts streams and editting them nicely. Right now it only saves to .mpeg and elementals.
post #352 of 2773
I have used videoredo to edit TS files and it does work well. Their audio quickfix also works really well. I was reading on their forum and you can now save as a TS file type and not just MPEG. You have to enter a code of some sort somewhere and then it enables it to save as TS. Great program that keeps getting better.

Just found the link to enable TS as an output type in the videoredo beta.

How fast it is compared to HDTVtoMPEG2 and does it affect the video quality after editing and what's the size file limit? I already tried 19GB .ts file and it won't accept it, it displays an error message: No PIDs specified when trying to open a TS, So I had to uninstall it from my computer.

I haven't used HDTVtoMPEG2 so I can't compare. I haven't had to use it in a while. I used to have to run the quick fix option so my roku hd1000 could play them better. But since the firmware upgrades to the HD1000 I don't have too any longer. I have opened TS files that size without any problem. If I remeber, I will try to use it a bit tonight....

ctdish, thanks very much. I downloaded some more players and now I also get them to play at the proper lengths that you posted.

Right now, I don't have DirecTV or Dish Network, but based on everything I've read, the bitrates for SD streams for both of them are generally from 800MB to 1500MB per hour. I calcuated the bitrates for these two samples. The bitrate for the Dish Network clip is 2584MB per hour, and the bitrate for the DirecTV clip is 2159MB per hour. The DirecTV bitrate doesn't seem too much out of the norm, especially given that it's a premium channel and looks really good. The Dish Network clip seems way too high, especially given that it looks much worse than the DirecTV clip. There are a lot of compression artifacts.

What you do you guys think? Since I don't have DirecTV or Dish Network, I really don't know. R5000-HD, is it possible that the first one is compressed from the original Dish Network source in some way? Maybe it somehow gets compressed coming from the receiver?

The most imprortant thing to me in what I get (right now I just have analog cable) will be whether I can losslessly save the digital stream. If I couldn't get the digital stream with Dish Network for some reason, then I'd get DirecTV. And if I couldn't get the digital stream from DirecTV, I'd just stick with analog cable.

I belive the samples are a constant bit rate transport stream, so you can't use the file size to calculate the video bit rate. Download TSReader from www.coolstf.com It will tell you the bit rate of each of the bit streams in the TS.

Nope. compressing / recompressing takes lots of CPU. the R5000 folks said that they don't recompress they just faithfully capture the bit stream. Directv correctly uses 3:2/Telecine mode to get a lower bit rate for the same quality level. dish does not, everting is encoded as 29.97 Hz interlace frames (even for film sources).

Goto your local Radio Shack and check out the Satellite channels. The non-premium and local channels are heavily compressed. But PPV and the other pay channels are about the same quality as digital cable.

I have dish. If you want to convert SD transport streams to DVD VOB files, use the replex utility on r5000 support page. directv uses long GOP structures which aren't compatible with the DVD VOB format. I don't have directv, but I suspect you could convert the SD TS to DVD VOB, but the resulting DVD might not play on some players due to the non standard GOP.

That's not true. DISH uses adaptive inverse telecine and progressive frame coding on their SD channels.
post #358 of 2773
And Directv is 1280x1080i on HD. Dish on most HD sources except 6 Voom channels is 1920x1080i.
post #359 of 2773
I just downloaded VideoRedo Plus and works with .ts files, however it does affect the video quality the original video is much sharper than the video edited, and it takes more time than HDTVtoMPEG2 and the output file is not realy .ts even if you choose the option .ts output, on my computer the file holds WMP icon while the original file holds VLC icon, So I decide to keep HDTVtoMPEG2 it's the best software for the actual time.

We should take the editing discussion to another thread.

Are you sure that the VideoReDo output was not as sharp? It's my understanding that VideoReDo/Plus has the ability to output without re-coding the video. Is there an option for that? Did you have it turned on?

The type of icon that you see for the output file has only to do with the filename extenion, and nothing to do with the contents of the file. Did the output have a different extension than the input?
