I use comskip (paid version) to scan the WTV files for commercials. ShowAnalyzer does it with the free version, but failed on too many of them.
Apps that convert WTV to MPG or DVR-MS are just doing a container change. But maybe you WANT to transcode it if sending to something other than an extender because a) mpeg-2 is pretty crappy compression, so HD recordings may be a higher bitrate than your WiFi, and b) H.264 has more modern hardware support.
I may in time make some changes and look into other possibilities, but for now, I'm really only using the HTPC itself for recording and playback. I like the full experience, and the HTPC is connected to my surround system and plasma, so I tend to only watch video when I can utilize that.
Sometimes I'll watch TV in my room, and at that point, it's either streaming services or, if desired, I can watch and record live TV using my desktop (which also has Windows Media Center), since I am using an HD Home Run on the network.
If I get into transcoding into H.264, it'll be because I actually got much more interested in remotely streaming when I'm not at home. I utilize Remote Potato for that at the moment - mainly for the remote scheduling, but I think if I switched to smaller files it could stream better. That, or also install a server like Plex on my HTPC.
Now, regarding Comskip - can you continue watching the recordings within WMC, and the tagged commercials can be skipped/are auto-skipped right there?
I'd like to keep the HTPC very streamlined, in that absolutely everything possible occurs within the WMC interface for the sake of easier operation with my Harmony remote.
Once configured, I imagine Compskip itself runs in the background and starts working whenever a new recording gets created in the directory? Does it work like, as in I can record a show, and start watching the show and skip commercials while it is still recording?
I did just see that Comskip cannot read copy-protected recordings.
I do record some TV that is DRM-flagged. Is there any way around that? With container-changing, transcoders, or anything?
