Compressing OTA (ATSC) Live TV using h.264?

[securitnick]

So I am a virtual cord cutter meaning I just cancelled satellite. I've got a Windows 7 machine running XBMC and using NPVR for the PVR backend. I have a Happauge 2250 capture card receiving OTA channels. Everything is working pretty nicely (except I can't get a remote working for the life of me...but that's another post). My question is if anyone knows of a way to use h.264 compression to when recording? It's my understanding that by default, it is broadcast using MPEG2, but this leads to very large files. I have a 3TB drive for storage and the other day about 1/3 of it was used up from my live TV buffer. So I'd like to figure out a way to compress it using h.264. Any ideas?

You can't do anything with live tv.

The live tv buffer is designed to rollover and even with 5 clients you shouldn't need more than 50GB assigned to it. Your best bet is to find out what is filling the drive and get logs to sub to help him fix it.

Where do I set the limitation to the live buffer? I haven't come across any setting that will allow me to do that.

The default for xbmc is 21 minutes per client which is only 4GB, why bother?

I'd prefer to have it record an hour, but the length of time doesn't really make a difference because it continues to record and build up in that folder. There doesn't appear to be anything to either 1, recycle the data (record for x amount of time, then delete the oldest and record newer), or 2, put a cap on it to stop recording. I can't really figure out what's causing the video to stop recording at all, but it's not simply exiting out of XBMC because it appears to continue to record some. And as I said, it just continues to build up in that folder I have set up for the buffer until I have to manually delete it every couple of days.

It appears you are actually suffering from the bug described here http://forums.nextpvr.com/showthread.php...g-playback (among other threads) which has nothing to do with the buffer size. If you are running Windows XBMC Frodo manually installing this http://forums.nextpvr.com/showthread.php...post454442 might help.

I'm guessing you are referring to the zip labeled XBMC_NextPVR_win32.zip? Does it matter if I'm running 64 bit Windows?

[mvallevand]

That file and it is 32 bit because xbmc is still 32 bit which is why you need to install this in the Program Files(x86) folder overwriting the newer version (respecting UAC too)
