Noticed that too, but haven't got around to finding a workaround yet. The problem is also there using the preferred (non-suid) method in the official howto. Could it be a bug in svn??

As i'm struggeling with some quality issues myself, are you sure the problems ar at the input side? Met vriendelijke groet, Micha Kersloot Hi, Pretty sure. There was a BIG difference between 0.5.1 / the firmware from the ivtv website link, and 0.3.8 and the firmware from my CD (sorry, I'm at a different box so no md5's this time). I'm not sure that the coax connector on the back of the pvr-500 is optimal (feels a litle loose), so I may be losing some signal there, but I do remember things being much better, and quite acceptable back in the 0.3.7 days. Trouble is live TV from Myth has been broken since I rolled back ivtv and I haven't had time to fix it (probably won't until after Christmas). So I can only see the results from MPlayer. I might try different firmware and/or 0.4.(1) if I get a chance. What kind of problems are you having?

[mythtv-users] recommended ivtv and firmaware versions for PVR-500
Hi, Now that sound is (kinda) working I can devote myself to fixing the terrible quality from my PVR-500. I'm currently using 0.5.1 with the following firmware: 5f5fa240ada73c3565f5f7de4c7b5138 /lib/firmware/HcwFalcn.rom symlinked to v4l-cx2341x-enc.fw 3a4803384f749d644ee1f1ca9dcb12fa /lib/firmware/HcwMakoA.ROM symlinked to v4l-cx25840.fw The tuning woes thread suggests that iovtv 0.3.8 is the most trouble-free version and as I had good results with 0.3.7 I'm considering trying this first and using the firmware from the cd (as before). Only problem I can think of is that the 0.5.1 stuff included a rebuild of v4l, so presumably I need to recompile all my v4l stuff from the vanilla kernel source before I can use older ivtv drivers. Is this true? Any better suggestions for PAL cards? Cheers Marius ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
