Hi,
I found an old Medion MD5044 tv-tuner card which I popped into my mythtv as the only tuner card. I used xawtv to find the "frequencies" and configured mythtv accordingly. Watching tv with mythtv works (as it "it shows the right picture") but it stall all the time and get further and further behind.
My system is an (old) AMD Athlon 1.1GHz machine with 1MB memory and a brand new (fast?) 250Gb harddisk.
I've ordered my pvr 350 but would like to get a feeling of whether I should ditch my old tuner card or leave it in.
Needless to say, it works just perfect with xawtv which doesn't write everything to disk first.
The default recording resolutions and bitrates for MythTV are a bit high. Try lowering the resolution to something like 352x480 and record using MPEG-4 at a bitrate of 2200 (1 GB / hr). You should find that it works much better and then tweak the LiveTV bitrates/quality options up from there if it works. You will also find that if you don't watch something while recording you can use higher bitrates for recorded shows using maybe the High Quality profile since the system will not be playing back at the same time.

Somehow I doubt this will work so well even with a lower resolution. I have a Celeron 2.4 GHz and it barely copes with Live TV at the settings you list. If it DOES work, then I have some other problem. I hashed through this pretty thoroughly on the list 2-3 months ago.
That's basically my point. By default MythTV uses much higher bitrates and settings that a lower end system can handle from a recording standpoint. The best practice is to lower the settings to what works and then tweak back up to the best that can be done with the given hardware.

I use a P3 733 system and to watch "LiveTV" I had to lower the resolution, switch to RTJPEG, lower the bitrate, and switch to uncompressed audio. Start with uncompressed audio, then lower your RJTPEG quality a bit. After that adjust your resolution down until you have some CPU idle time. Then you can tweak any of them you want. I takes a while to get a combination that still gives reasonable quality but with patience it can be done.
