hey guys, I don't know where the problem is really coming from. I am using air2pc pci card to capture OTA. I'm also using Mythtv for my pvr. I was using feb 23 cvs of mythtv and everything is fine, no issues. I tried the latest mythtv cvs yesterday compiled with dvb. I noticed that when watching OTA FOX channel 32, the audio is very cracky. However, I don't see any issues when watching other HD channels like WTTW 11. Someone on the mythtv-users told me that other people are also experiencing the same issues. He told me to use TS rather than PS. I will have to try it tonight. So any comments on this? Thanks, Neil
