...well. MythTV h264 seems to be crappy in general. Even new and
powerful systems are affected by this. Hopefully the new Hauppauge
device will help get those issues sorted out.
As things stand right now, I happily use an external player for
all of my h264 content. Given the features I've cobbled together
for myself, that will likely not change. Although I do hope that
MythTV can exploit the HD PVR in a timely fashion. Realtime h264
transcoding would be just too cool. It doesn't even have to be HD.
