Post subject:  how to change the default recording format.
i know that mythv defaults to a *.nuv file when it records a show. is there any way i can change the default format? or is there a hardware restriction (like u need rele powerfull hardware to do it in another format?

where would i go to change this (a config file...) i know i can change the "profiles" in myth's menues but how bout being able to change theactual format. 1 gig for 1/2 hour is a tad un acceptible. but transcodeing is suposed to shrink the files down. how can i adjust the format it transcodes into?

thanks for the help.
PS, NONE of the 15 shows i have, have sucessfully transcoded themselves. so i think thers somethigng wrong with the transcodeing. (the logs say errored on all of them)
i will get a log up soon (i think i know where its stored. but if somebody wanted to help me with that i would be apprechiative.)

so thanks for the help.

If you have a "software tuner", you cannot. Hardware MPEG tuners, DVB and HDTV tuners are all recording in MPEG2. In these cases, .nuv is simply the extension.

ya i got a software tuner. guess thats what i get for being cheap ;) still can it be saved (by the cpu) in a different format. or is it to CPU intensive?

I thought you could choose whether you used MPEG4 or RT-JPEG in the recording profiles. MPEG4 encoding requires a bit more grunt, but my athlon 1700 XP could manage it at PAL DVD resolution (720x576), but couldn't quite watch it while it was recording.

You can edit the Recording Profiles somewhere in the TV Settings menu i believe.

You are correct sir.

yes you can choose either of those formats, though neither is going to play on anything other than mythtv unless you have special codecs installed.

Strange that the 1700+ couldn't do livetv using that resolution, because my 1700+ has no problem whatsoever doing 720x480 using MPEG4.

You may not be able to play them elsewhere, but if you have the grunt to record in mpeg4, it beats either having to transcode or having 1 gig per half hour.

The problems playing back on my 1700+ were minor. It was taking 60-70% to record and around 30% to play back. So it mostly worked, but had the occasional skip.

Remeber PAL DVD res is 20% bigger too (although I guess the frame rate is 20% less... hmmm).

I think I run my FSB at 100MHz instead of 133 because I was having memory problems, so I loose out there.
