I realize that i am not running a supported os on the server side and adding bda support was a bit of a hack job but i am wondering if my problems are related to that or not.

When tuning to a clear qam channel mediaportal hangs (no black screen or anything, just frozen) for anywhere from 30 seconds to 10 minutes before the 1080i signal actually kicks in and starts playing on the client. I have tried tuning multiple times and each time the wait is different. SD Analog tunes and is played within seconds on the client.

On the client when mediaportal finally does start playing the stream it is live and plays without any issues.

As a test i tried tuning with the mediaportal client and connecting to the stream with vlc at the same time, vlc is able to view the stream immediately while MP is hung.

I have tried ditching rtsp in favor of the network share method with the same results.

Also on a likely unrelated problem i receive an error on the server when stopping the stream relating to accessviolations.

i have attached the logs for both the server and client. The sequence of events is as follows:

Start TV Server
Start Mediaportal Client
Tune in MP ->Approximately 19:47:30
Streaming Starts ->Approximately 19:54:00
Stop Stream ->Approximately 19:54:14
Close Mediaportal Client
Collect Logs

Any help would be greatly appreciated.

so i have decided to switch my server back to server 2003 x64, the access violations when closing the stream are no longer present however i still have to same problem with viewing the 1080i stream.

for further testing i am now running a singleseat installation with a q6600 + gtx 260 and windows 7 x64 ENT. The problem still occurs but i do not see anything in the logs that point to an obvious problem.

i have tried the following codecs all of them with the same results: power dvd 9, FFDshow, MainConcept (HCW), Microsoft DTV-DVD

i noticed that mediaportal seems to kick in and start playing whenever there is a change in the stream, jumping from a show to a commercial for example. commercials are usually every 15 minutes on the quarter, if i start streaming at 1:05 (while a show is playing) MP will hang until around 1:15, the exact start of the commercial is the first thing i see. if i start streaming during a commercial MP will hang until the show starts ~1-3 minutes.

I have no idea why this problem is occurring. Can someone please have a look at the logs?

started streaming at roughly 14:43:29, hung until 14:44:47
