This is caused by the time it takes to delete the old ring buffer and the time it takes to prebuffer the new channel. 5 seconds is actually pretty good. That's about what mine is doing (700 Celeron). I've read things such as changing the file system, getting better computer, etc. but the best you are going to get is 3 seconds or so because of the prebuffer stage. You need that 3 seconds to make sure are sending complete mpeg frames to your card.
I just checked the "always use browse mode when changing channels in LiveTV" option in tv settings-> playback near the end. This will pop up the OSD and allow you to scan through what is on the channels quickly. When you find something you press "ok" and it will change to that channel. It will still take 5 seconds but you only have to do it once. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jeffrey Zellman Sent: Saturday, March 19, 2005 11:28 AM To: [email protected] Subject: [ivtv-devel] PVR 350 Tuner/TV Out Question (tuner 47) Hi, So the tuner and tv-out both work on my pvr 350 (tuner 47) card using ivtv 0.3.2i., but I had a couple questions.When I change channels with ptune-ui or through mythtv, it takes around 5 seconds for the next channel to display. Is this caused by the tuner or will the channels change quicker if I was using a better system. My system is an 866 Mhz pentium III with 256 megs of ram. Also when using the TV Out, to display my desktop, a lot of the desktop is cut off. Is there a way to change that.
