Well sorry for starting another thread, but the previous one is already 15 pages long and doesn't seem to contain anything useful to me at this point.

I started by using MP without TVserver and it worked quite well, but as an HD channel was added on the cable network, I wanted to have it listed and working on the HTPC as well. Apparently I need TVServer for that, and it is a nice exercise for fun too. Or is it ?

So I tried first on the boys' machine (abit IP35, E4600, FireDTV). Installed as a single-seat with mysql as a database. TVserver runs, and MP gets the channels lists, EPG data, but "no video/no audio" is being streamed. I thought it would work better in the HTPC machine in Vista, with newer FloppyDTV and SQL server, and I have the same problem.

Without TV server, MP finds all channels and works perfectly on both machines. TV server finds all channels but doesn't seem to stream any video/audio content to the client, either in single or multiseat configuration. I tried many builds, matched MP SVN and TVengine numbers...

The VoomHD channel works fine too with both FireDTV and FloppyDTV tuners, using DVBviewer or the FireDTV application, with CoreAVC, LEAD AVC or PowerDVD7 H264 codecs. Que pasa ?

I'll be happy to provide logs if it helps.

That would indeed help

Here are the log files, as should have attached in the original post, my apologies.

Seems like the timeshifting files are locked.
TsWriter couldn't create it.

[lsandini]

Thank your for your quick reaction.

Someone else suggested to place the timeshifting files on the C:\ drive instead of a drive with a higher letter or a shared folder. I selected the root of C:\ and believe it or not, preview now works in TV server, and I can see my FTA channels in MP connected in a single-seat configuration. I see my timeshifting files behave normally on the C:\ drive, growing to the predefined size.

I tried to place the timshifting files again on F:\ and I got the "no audio/video detected" while trying to timeshift or preview channels manually in TV server, and I could not see any stream in MP.

So could this be the beginning of a solution ? Anyway, I could not see encrypted channels (SD or HD), MP says that it could not start timeshifing as the channels are encrypted, although the decrypting card is inserted in the conax module.

YES, YES, YEEES !

Upgraded to today's MP and TVserver SVNs and finally it works !!!

I get all my channels, HD too in MP using TV server in a single-seat config.

Getting ready to change a few little things and transfer the HTPC to my living room

Sorry to bring it on again, but the fun lasted while it lasted, and it didn't last long.

I didn't post for a while as I was trying various hardware/ software configurations, but I am still stuck !

I could list all the builds I have tried, none seems to work, and my one and only problem is still the same.

After installing TV server and the lastest MP + plugin, I can see all FTA channels on my DVB-C FloppyDTV, as well as the first scrambled channel I tune to. After that, all efforts to tune to another scrambled channel end up with the "no video/audio" error, or " could not start timeshifting, the channel is scrambled". Rebooting the computer, restarting TVServer, upgrading builds, won't work. Only a clean new install allows me to watch once one scrambled channel, then nichts, nada, niente, rien, nothing, ei mitään.

My logs have shown that the .ts files are locked to 0 bytes, but deleting them or selecting a new folder/hdd/ramdrive for the timeshifting files won't correct the error. Tuning back to a FTA channel allows the timeshifting function to work normally again for FTA channels, whatever the .ts files' location. But not for scrambled channels.

So what is wrong with creating new .ts files when tuning to the second scrambled channel ? Something still missing in the TSwriter.ax file ? Any fix for that ?

Judging by the numer of reads in the "no video/audio" threads, the problem appears to be quite common, and appears with all kinds of hardware and software configurations...

As always, I am respectfully and patiently hoping/waiting for a fix

Hello all,

Still looking for a solution to my "no audio/video detected" when tuning to encrypted channels with FloppyDTV and TV server.

Apparently the ability to start writing the timeshift file is linked to the decryption process. In my case the timeshift files are locked to 0 bytes when tuning to encrypted channels, and works fine with FTA channels.

I noticed in the wiki a list of CAMs, some being tested, some not.

I wonder if my el-cheapo Conax module from the local supermarket could be the item causing trouble. Again all the channels show perfectly and even the HD channels are descrambled correclty in DVBviewer, so the CAM is not faulty. But maybe another revision would be supported differently ?

I need a new CAM anyway for other purposes, so here is the occasion to test this. Any comment on what I should look for ? The list of CAMs says Alphacrypt firmware 2.03 modules are tested, 3.09 are not.

I think many people should read this, I really hope it'll be the end of many headaches !

So I went out to find a new CAM for my FloppyDTV and FireDTV, and I found a Technisat Conax module at a local supermarket. Swapped CAMs when I got home and BINGO !!!

TvServer working with all encrypted and FTA SD and HD channels, in single and multiseat !!!

So it was a descrambling problem with the LA Digital CAM module that was the reason for the timeshift files being locked to 0 bytes. I realized there might be some other issues causing the same symptoms, but my problem is solved.

HTH
