Re: [Freevo-users] audio behind on tv recordings
Have you tried dumping the stream to HD and encoding offline? (this takes big HD). not tried that but that is an option HDD=250G I have a USB DVB-T card and I do that for recording: first I dump the stream to the HD and then I encode it with the encodingserver (I'm using Freevo-1.7.0-rc1). I only have around 25Gb free in my HD for recordings and I haven't had problems. 2 hours in mpg are about 5Gb, and encoded in xvid 1200bps only 1,3Gb (in my PIV HT 3Ghz, 512Mb RAM the encoding takes 1 hour for 2 hours of recording).

What else do i need to check? Well.. I gave up and bought a DVB-T card. THis way teh stream comes interleaved. I think there are some syncing problems which come from some clocks on some sound cards. I think CPU is a synching problem source, and I think mencoder just struggles to record TV. So, what is your mencoder command? Have you tried dumping the stream to HD and encoding offline? (this takes big HD). Are you recoding sound off the card directly or sound input through the soundcard?
