[QUOTE="sjeffrey, post: 747195, member: 81884"] Wow, I left for a weekend and 3 new pages to read.:o Does HDMI actually do MPEG2? I know this isn't an issue with component cables since it's in analog format but HDMI I'm not familiar enough with. I would assume that it's Colossus' job to decode the MPEG2 and then it will still encode as MPEG4, I don't suspect that will ever change. So for TVServer and MP Client, it's always MPEG4. You guys have been talking about a longer pause for channel change and pmt versions for a bit. My take on it is that broadcast changes will still cause issues so a longer pause won't fix it. I still haven't tested Colossus with AC3 but with HD-PVR you can tell it's the hardware that has a "hickup" and not MP (the bling led flickers for a few seconds then back to solid). A recorded show in AC3 has no issues with commercials switching to 2 channel and then back to 5.1 so we already know MP can handle the switching from 5.1 to 2. Live TV on the other hand is different. It seems like HD-PVR stops sending data to handle the change and then starts sending packets again. Since you are playing back the live stream it's like you just hit a wall and can't go any further as there is no data to read. This is experienced as stutter in the client. Our "workaround" has always been to pause for 2-3 seconds and you would be fine for a while. This makes sure you won't hit the end of the stream again while HD-PVR switches format. Video, like WileE said, is a non issue probably since so far all STBs are fixed format. And more about the pause, I think we have all tried over the years to add, remove, make longer the pause after a channel change but we never got 100% success. BTW, I know SageTV has a configurable pause for the HD-PVR but I never tested Sage much to know if it's actually better for handling the PVR. Well that's my input on the issue. Hopefully I'll have some free time soon. I've been spending all my non-working time on home renos... [/QUOTE]
