Hi John,
I use ffmpeg to squish my recorded tv down for my iPad (using my own front end rather than scripts) and have not experienced the 'streams' problem there.
I use VideoReDo for editing and mux the wtv's out as dvr-ms. When WMC first changed from dvr-ms files to wtv I got 'elementary streams' errors frequently from VideoReDo and still do, very occasionally, when there is an error in the recording.

That makes sense and what I originally was following up on as MCE appeared to be giving me the option to select one of the streams.
What version of Windows are you on? Did you replaced the default codecs MCE uses when you installed ffpmeg (Win7 doesn't want you to)?
Am I understanding correctly - that your recording are working OK (inside MCE)?

This is MythTV 0.26-fixes under Fedora 17 (Linux), so I can't relate directly to experience under Windows. I posted because people were concluding that something had changed but didn't know what. This is a real change, I don't see any causal link to the PSB1 retune, and no-one else on the MythTV lists has reported seeing it. My recordings are fine, but I had to modify the part of my editing script that selects the streams I want to keep: select "mpeg2video (Main)" instead of "Video". I don't think many people regularly do this sort of edit.
Does MCE have an "mpeg2video (Main)" codec?

Ah, OK.
If I am understanding you correctly then it sounds like a change to the multiplex that you can, manually, cope with in MythTV but we can't (yet) in MCE? Also, our TVs (well at least mine) doesn't have a problem.
Not sure I understand your Q 100%, sorry. Win7 ships with codecs for all the major compression 'formats' and I know of no way to tell MCE which stream to use. It appears to give me this as a manual option within MCE but it doesn't work for me.

My Panasonic TV, and MythTV, have no problem with PSB2. My editing script looked for streams recognised as "Video" by ffmpeg, and suddenly found 4 in individual channels of PSB2. Now it looks for "mpeg2video (Main)", finds just one, and works again.
I asked on the MythTV list if any other transmitters had this. Only one response so far. Winter Hill Chs 4 and 5 DO NOT show multiple Video streams with ffmpeg. I suspect a misconfiguration of the PSB2 feed for Waltham.

I have added before-and-after extracts from my logs from the ProjectX demuxer to the thread on MythTV-users that I quoted on 20 June. They may help. Both recordings from Waltham, Channel 4.

Guys,
Does anybody have a fix for this issue? I have 2 htpc's with different tv tuners in them and both exhibit the same fault. The has to be a way to fix this? Because my whole setup runs on mce and extenders. It would seem that either Microsoft or the broadcasters should be able to remedy the situation. I am sure that Microsoft will suggest that the issue lies with the broadcaster since the problem didn't exist until after the change over.

Still having the same fault. I'm having to use my single freesat tuner to help cope. But no very ideal.

I am using WMC in Windows 7 with a Kworld KW-PC160-2T duel tuner card, I am in Alvaston, Derby
Previous to the retune on May 13 this year, which was required because Public Service Broadcasting on Mux 1 (BBC1, BBC2, BBC3 etc.) was moved from channel 61 (794Mhz) to channel 49 (698Mhz) I would occasionally lose those programmes on Mux 5 (754Mhz) (Pick TV, Dave, E4+1, etc.).
This above problem has persisted for about 18 Months.
Since the 'retune' I have lost the programmes on Mux 2 (737.833Mhz) (ITV 1, Channel 4, Channel 5, ITV 2, etc. but the good news is Mux 5 has not exhibited problems since.
I have been pulling my hair out and then scratching my bald scalp trying to find out why? As previous posters have noted, these programmes can be displayed using VLC so why not WMC?
