This thread has me wondering, now. I just got MythTV going and
have done some test records.
The Simpsons Halloween special recorded just fine, but it was in
SD format(Recorded from the HD channel). That same night, I tried to
record Law & Order:CI. That recording had a lot of breakups and qudio
dropouts.
The system is a 3.06GHz P4 with a HD3000 and a Rosewill Nvidia
5200FX.
My understanding is that recording DVB streams is not CPU
intensive. The card just grabs the digital data off the air and the
system writes it to disk for later manipulation/transcoding. Am I
correct?
That is my understanding of it as well, and what I see in practice.
Recording a show hardly loads the CPU at all.
If that is true, then I am casting a suspicious eye to problems with
reception. I know that there is one channel that MythTV's scan didn't
pick up.
So I guess my question, is how can I tell if the problem I'm
seeing is trouble with recption vs. a possible system throughput issue?
It is hard. I would expect that true reception problems would be less
frequent and VERY random. I have yet to see a true reception problem on
mine - I am lucky that I have very good reception. Also, reception
problems would not correlate at system load and especially disk I/O.
Try starting a large file copy on the SATA drive while watching live TV
under Myth.
