Unable to watch DVB-T input through PVR350 hardware decoder (IVTV)

Description
As far as I can tell DVB-T recordings are recorded as MPEG-TS and these are replayed on the OSD of the PVR-350 through the X-driver. This results in very jerky motion, as the OSD is nowhere near fast enough for this purpose. When watching recording made from the PVR-350 itself (MPEG-PS) the hardware decoder is employed and it works great. My current workaround is to "replex" the file in the filesystem to MPEG-PS. It plays back fine then, but discards information such as aspect ratio and subtitles, apparently.
It used to work (somewhat) with mythtv-0.18.1, but that was probably due to the fact that it was setup to convert MPEG-TS to MPEG-PS while recording. I have noticed a ticked (#222) saying that this was then switched off, as it ruined too many things, and that MPEG-TS replay should be usable instead.
I used the gentoo package, SVN#8642 for testing, IVTV-0.4.2, Linux kernel 2.6.14-gentoo-r5. Hardware is 2xPVR350, 1xNova-T.

1) The pvr-350 decode is extremely limited in what it will successfully decode. Random stuff from DVB-T recordings likely will break it often.
2) Set up the X driver better so you have Xv support.
