I upgraded my PVR box to Core 3 recently and I am having issues with a couple of items.
1) The driver series greater then 0.3.1r give me errors such as:
ivtv: OSD: DMA xfer from 0xb7efb7d8 of 655360 bytes failed with (-512) offset = 0x000b17d0, total 1382352
I noticed that in 0.3.1s a patch was added to fix DMA issues in kernels above 2.6.8. Apparently the stock fedora kernels don't have whatever issue was being addressed.
2) The only drivers I have been able to get work with MPlayer's ivtv patch is 0.3.x series. All other drivers seem to complain about invalid arguments to mmap'ing the device and then I get errors about "Error with sending DMA to ivtv". This has been mentioned several times before on this list without resolution.
3) The mythtv backend (0.16 and cvs) will segfault (without core) after an hour of recording (two 30 minute programs). I don't think this is entirely a fault of mythtv on Core 3. I have tried debugging the backend a couple of times unsuccessfully, but when I have ... I have caused the ivtv driver to start complaining about ivtv: "ENC IRQ OVERFLOW: #4007 Stealing a Buffer, 320 currently allocated" I think some condition that ivtv is creating under Core 3 is unexpected in the mythbackend. If anyone is running mythtv and core 3, please let me know what kernel, driver version, etc you are using. I will continue to investigate on this end.
