Yep, I tried reformatting from reiserfs to ext3 but the video is still 
choppy. It appears that this is a problem with the CPU. mythfrontend is 
running at about 180% CPU on a Pentium 4 2.4GHz with hyperthreading in 
LiveTV mode. I've turned off any deinterlacing of the playback stream.

Does anyone have experience with the pcHDTV 5500 card? What are the CPU 
requirements for this card in LiveTV mode?
