The primary goal of the IvyTV Project is to create a kernel driver for the iTVC15 family of MPEG codecs. The iTVC15 family includes the iTVC15 (CX24315) and iTVC16 (CX24316). These chips are commonly found on Hauppauge's WinTV PVR 150/250/350/500 models TV capture cards. More supported cards can be found at their website.

I've found some stuff for configuring my PVR350 tuner card that I am having problems finding info for. Under the Settings->TV Settings->Recording Profiles->MPEG-2 Encoders (PVR-250, PVR-350)-> Default->Video Compression settings, I find an option for Stream Type that has many options. The default is MPEG-2 PS. Some of the other options are MPEG-2 TS, MPEG-1 VCD, PES AV, PES V, PES A, DVD, DVD Special 1, DVD SPecial 2. Can anyone provide some insight into what these settings are intended for?
Well, TS and PS are the standard transport and program stream respectively. VCD is mpeg1 compression and will give a VCD compliant stream when used in combination with the proper resolution and bitrate settings. The same for DVD and DVD2, those are DVD compliant mpeg2 streams which will give an mpeg2 stream which doesn't need to be replexed when it's in a compliant resolution and bitrate. DVD2 is the streamtype MS MCE uses and therefore should be the one the firmware is optimised for. So I use this one. If there ever is a DVD burning module I'm prepared
