Working on 32-bit OS, Vanilla kernel 2.6.21.1 (FC6 base installation), with PVR-150 and PVR-350 and Freecom DVB-T USB, an Asus P4C800 motherboard, xdriver for PVR-350 out and MythTV (an older svn version) it looks all stable. Tested it with recording directly from DVB-T, PVR-350 and watching livetv from the PVR-150 out of the PVR-350 all at the same time. Pictures looking allright. I'm still tuning my IR in combination with MythTV. Will do some more testing. This was allready an older poblem in my setup. Also need to get my DVB-S configured into the system and will do some testing with just reading from the devices at the same time. I will let you know.
