I have the pchdtv hd-5500 (which is what I believe the card is you're talking about?) working fine with 13.1 (recently upgraded by fits and starts from 12.2) and MythTV.
But since I use this card on the Slack machine together with 2 Hauppauge 1600s and an AverMedia A180 saa7134 card, whose modules/sources seemed to be absent from the kernel tree, I confess that the very first thing I did with the 184.108.40.206 kernel before firing up any of my tv cards was to download the daily v4l-dvb driver source snapshot from http://linuxtv.org/hg/v4l-dvb
, compiled the whole shebang and installed it. The cards all thereafter started without incident, including the pcHDtv 5500, and run fine.
Now you may have some specific TVtime problem, which is software I have no experience with. But otherwise, you may wish to check to see whether output from dmesg and lspci gives you any feedback regarding whether your pchdtv card was detected/loaded properly at boot. You may wish to check with lsmod to see whether the modules are in fact currently loaded for the 5500. If using some kind of custom kernel make sure linux video is enabled in the particular kernel. You may also wish to compile and install your own v4l-dvb driver set from source.
Those are some initial considerations.
