Did not have seen a/v sync problems for recordings up to some hours and don't know if there is a limit. I'm testing on it to see some proof of concept and WebVCR+ is waiting too. Mencoder gives no sound for me to the recordings over the v4l1-compat on saa7134-0.2.7 and 2.4.20-v4l2 and so freevo is not yet an option. (Would be interesting to have a list, where it is working. I allways waste time on it again :-) What I see working is timeshift using xine, in my case with a second audio card with alsa 0.9.3c and OSS emulation. This works even over nfs mounts. Jumping forward and especially back is a little bit unprecise, but play back is straight forward ;-) With xawtv in overlay mode you can have at the same time a preview of the nvrec recording in realtime. (Take care, if you quit xawtv the sound for nvrec is also closed). Muting sound on the record input with kmix works, so I don't have to switch anything manually to avoid to here sound twice. The saa7134 driver is still under successful devel, especially on audio. There are cvs-builds and other snapshots involved here ... so results may vary especially for bttv, which I don't have in use. > My system is as follows :- > [snip] Hope you get some luck, keep some hair and get WebVCR+ working.
